Arecibo Observatory


The AGC

The AGC, or Arecibo General Catalog, contains information about the positions, sizes, magnitudes, morphologies, redshifts and HI properties of lots of galaxies. It is very heterogeneous, so it shouldn't be used as the ultimate authority on anything! But, here is some info on its status and a summary of what it contains; formats refer to the ASCII text version available to the CU EGG.

Latest news
UPDATE IN PROGRESS Dec 2013.... ASK MARTHA     The Jan 2014 version is more-or-less up to date in the north out to cz=18000, as of Dec 2013, but since new objects are being added by SDSS fairly regularly, it is not perfectly up to date. We make changes as time permits, and make big updates 1-2 times per year. A serious caveat: to avoid duplicate entries, our algorithm does not add an object to the AGC if there is already one there within 2'. So it is probably not complete in crowded regions.


Even this documentation is incomplete! And imperfect! For more details, you will have to ask Martha.


Remember the rules of use.

                          The AGC files:

     The AGC files contain all of the information from D. Burstein's version
     of the UGC plus all galaxies with known redshift from the privately
     circulated catalogs of J. Huchra, L. daCosta and Giovanelli-Haynes.
     The file also contains HI data from the Fisher and Tully catalog
     (published) and other selected sources. The status of coverage is
     as follows:

Note 1  The UGC is the Uppsala General Catalog (Nilson, 1973); a copy
        is available in the reading room. Further information on the entries
        can be obtained from reading Nilson's introduction to his catalog.
        The ESO catalog is a version based on Vince Ford's catalog and
        the entry number is simply a sequence number within that catalog
        (note it is meant to be used only as a pointer privately).. The
        ESGC catalog has been privately communicated by Harold Corwin.
        A permanent AGC is assigned when an object is added to the catalog.
        Sequencing is not retained if a position is updated, but assignment
        of numbers is made per hour of right ascension:
        100001-109999  0-1h north     400001-409999 0-1h south
        110001-119999  1-2h north     410001-419999 1-2h south
         etc. until
        330001-339999 23-24h north    630001-639999 23-24h south
        ****  NOTE
        Effective 2007 Jan 04
        Numbers above 700000 are used for objects in the north where there are
        >10000 galaxies per hour of RA. These are added sequentially without
        consideration of RA. ****
        The last number assigned per hour per catalog is listed in
        AGC.NUMBERS and AGC700000.NUMBERS
        Assignment of new numbers is done regularly using the program
        assign.f. Additional entries to the AGC should be entered
        first with sequence number "0". Assignment of new numbers should
        only be performed by MH.

Note 2  Widths measured as follows:
               Code         Measurement
              ' M50'        50% of the mean flux density
              ' P20'        20% of the peak flux density
              ' P50'        50% of peak flux density
              '5M2P'        average of (50% of mean) and (20% of peak) widths
              '2P50'        50% of each of the two peaks (if double-horned)
              ' F50'        50% level of fit to slope on either side 
			    (using 1991 msr algorithm .825 .5 .5 .2 .5)
              ' A50'        Similar to above, but using IDL_ALFALFA code
                            (including LBW observations)

Note 3  Telescope code:

               7  - Hybrid - corrected flux
               8  - Optical, or else unspecified radio dish (see Note 5,
                                                             HI Source = 69)
               9  - No observations made
               A  - Arecibo non-detection WITHOUT known optical redshift
               B  - Arecibo flat feed, corrected flux (normally mapping)
               C  - Nancay, uncorrected flux (we should change this)
	           D  - VLA
	           E  - WSRT
	           F  - Australia Compact Array
               G  - Arecibo Gregorian, 3.5arcmin beam, uncorrected.
               H  - HIPASS/Parkes multibeam
               I  - HIJASS/Jodrell multibeam
               J  - AO/ALFA
               K  - GBT
               L  - ATCA
               M  - GMRT

Note 4  HI detection code:
               0  - not detected/not observed
               1  - detected.
                    This is equivalent to CODE=1 in the ALFALFA scheme.
               2  - marginally detected; everything uncertain.
                    This is equivalent to CODE=3 in the ALFALFA scheme
               3  - detection, but inadequate for FT purposes. This
                    may mean width cannot be measured because of baseline
                    or noise on edge, or the profile is very asymmetric or
                    weird, or confusion is suspected. In this case, the flux
                    and velocity are usually measured ok, but one is not
                    certain what they all refer to.
               4  - HI profile shows absorption. Flux certainly affected.
               5  - Confused with obvious optical companion (i.e. confusion
                    is certain).
               6  - This means the width has been BOXCAR+HANNING not just simple
                    Hanning. NOTE THIS IS AN UPDATE TO PREVIOUS DOCUMENTATION!
               7  - Used for ALFALFA detections to indicate an object which is
                    detected at low SN but with apriori redshift. This is 
                    equivalent to CODE=2 in the ALFALFA scheme.
               8  - Profile obtained by some of us, but parameters not final
               9  - preliminary measurement

Note 8  IBANDQUAL - I1 - quality/status flag:

        0  -  Not observed
        1  -  Observed with photometric high quality
               (zpc*error < 0.05 mag)
        2  -  Observed; zpc error 0.05-0.10 mag
        3  -  Observed; zpc error 0.10-0.20 mag
        4  -  Observed; zpc error > 0.20 mag

        6  -  Fit performed on extant image is poor; image itself prob ok.
	          Usually means that fit cannot be done well because of bar,
	          face-on, asymm, etc. Correponds mostly to Q_EFIT=4.
        7  -  Unacceptable for imaging because of superimposed star,
              wrong morphology, etc.
        8  -  Observed; status unknown (data not yet
               reduced or unknown from other source)
        9  -  Must be reobserved for reasons other than poor
              photometry. Examples are:
                1) Object too close to edge of frame
                2) Image is trailed significantly
                3) Background level is too high (moon)
                4) Bad column of CCD passes through galaxy.

Note 12:  Flag indicating existence of digital spectrum.
      1 -- Spectrum of galaxy in the EGG HI pointed observations digital archive
      2 -- Spectrum available in ALFALFA archive (no ALFALFA 3s should be here)
      3 -- 1+2 i.e., both (no ALFALFA 3s should be here)
      4 -- Spectrum available in ALFALFA plus literature flux measurement

Note 13:  It is beneficial to know where the coordinates listed in the
AGC came from. This 1-digit code will allow us to identify the
source and hence the expected accuracy of the position entered into the
AGC. We should make use of this code in the future.
      1 -- From measurements made using digital pad
      2 -- From POSS prints with OVERLAY only (either 
           OSU overlays or our own).
      3 -- From DSS by DD
      5 -- Found using SKYVIEW
      6 -- Published positions
           UGC objects: Cotton et al. 1999 ApJS 125, 409.

      8 -- From SDSS SQL
      9 -- NED positions with accuracy quoted to be <2"

Note 14:  Identifier for existence of data in Palomar long-slit DBS
database. 9 means marginal or suspect data. Now updated so that
highest number from below is set in AGC:
      1 -- From Vogt thesis sample
      2 -- From Dale thesis
      3 -- From Jore thesis or misc Palomar Sa's 
      4 -- From Palomar band survey or other associated stuff
      5 -- Included in MFB rotcurve database
      6 -- TF scaling relations project (>= sep01), JD extinction etc 
      7 -- High z ORC's, either Palomar or KPNO
      8 -- Observed and detected but only 300 seconds or not extended
           {This code not consistently implemented, but will be someday...}
      9 -- ATTEMPT TO GET ORC FOUND NO LINES

Note 15:  Flag for objects that are listed in the RC3. A cross reference
file is maintained in /galaxy/rc3/rc3agc.cross. It should be accurate
except in some cases of confusion in multiple systems. In July 00, we 
updated magnitudes and diameters in the agc.south using RC3 scaling so
that 
   (a) for galaxies in the MCG strip with RC3FLAG=1 (-18  ext_I = 0.45*extrc3
          DIRBE   E(B-V) ==>  ext_I = 1.962*extdirbe
          NOTE: THIS HAS NOT BEEN UPDATED LATELY!!! MANY OBJECTS MISSING THESE VALUES!
