Description:
This catalog contains all radio measurements of optically bright
'normal' galaxies available up until publication of this compendium in
1975. The compendium was originally intended to simplify statistical
analysis of radio properties of these normal galaxies. No data
processing was carried out (except to bring the data into a consistent
format) and no identification was attempted. These data were
originally published as Haynes R.F., Huchtmeier W.K.H., Siegman B.,
and Wright A.E., CSIRO Publication, 1975.
The electronic version of this catalog has made small changes to the
original version in an attempt to better identify positions with their
source names. Where there was no entry on a line for the source name
or position in the published version, data from the previous line was
repeated.

Note (1): This column gives the name of the source. 'AN' refers to a
designation for anonymous galaxies used by Pfleiderer (personal
communication). The radio emission may sometimes originate in a region
containing more than one galaxy, and in this case the designation is
abbreviated, e.g. NGC4038 and NGC4039 appear as NGC4038/39. Radio
components of a specific optical galaxy are indicated by a suffix,
e.g. NGC4472/A, NGC4496/B and NGC3675/NUCL. In the electronic version,
the "/A", "/B", etc. appear on a separate line, so it is necessary to
use the name in combination with the position for a full
identification.
Where there was no entry in the name column of the original published
table, the name from the preceding line has been repeated for ease of
identification. Although in some rare cases, this may result in an
incorrect identification, we felt that it was preferable to always
have an identification listed, even if it is not guaranteed to be
correct.
Note (2): This column is marked with an asterisk ('*') if the position was
taken from the preceding line in the published table. Positions were
repeated this way in order to guarantee that every entry had a
position.
A 'C' indicates that positional data was added at CDS while preparing
this catalog. The information came from the name solver provided by
SIMBAD. Two entries have a 'P', indicating that the identifiers found
in this catalogs produced objects which were not radio Galaxies: NGC
7027 is a Planetary Nebula, NGC 2327 is an HII region, NGC 1769 is a
star cluster. NGC 7072 is a galaxy though, NGC 2337 is a galaxy, NGC
1679 is also a galaxy. Despite the high chance that these were just
typos, we left the positions empty for these objects.
Note (3): These columns give the errors on right ascension and declination
in seconds of arc. Errors in RC2 (de Vaucouleurs and de Vaucouleurs,
1964) positions are approximately ± 1' arc (Gallouet and Heidmann
1971A&AS....3..325G 1971A&AS....3..325G). In some cases, the error is listed as an upper
limit (e.g. < 1). When the position was repeated from the preceding
line, if there was an error listed, it was NOT repeated.
Note (4): This column gives the frequency (in MHz) at which the given flux
density was measured.
Note (5): These columns give information about the flux density. The
"f_flux" column uses the following symbols:
< If the flux density is an upper limit to the radio flux for
an undetected source.
> If the source was extended and the given peak flux density
is therefore a lower limit.
? If the flux density is questionable.
C The measurement of radio emission is confused by a nearby source.
Note (6): The "flux" column gives the flux density of the source, in Jy.
For the brightest galaxies (e.g. NGC0253), the difference between peak
and integrated flux density of the source becomes appreciable. Where
possible the integrated flux density is given in the table. However,
the reader should refer to the original reference to ascertain which
measure has been used in questionable cases.
Note (7): The "e_flux" column gives the error on the flux density given in
the original reference where available. Where no errors were quoted
the authors have usually estimated them at approximately one-third of
the flux density of the weakest detected source, thus assuming a 3
sigma detection level.
Note (8): These columns give the angular size of the galaxy. For RC
sources (de Vaucouleurs and de Vaucouleurs, 1964) the diameter is the
"face-on" diameter of the optical source, in arcmin. For radio and
other optical references the column gives the measured extension in
right ascension and declination. Optical sizes are given either as
major axis times minor axis or as a diameter "f_MajAxis = D",
depending on published values (e.g. RC2 or other) and is thought to
give an idea of the optical size of the galaxy to be compared with the
radio beam evolved with the corresponding measurement.
Note (9): The optical data included in these columns are taken from RC (de
Vaucouleurs and de Vaucouleurs, 1964) or from references with data
which are an improvement on the RC results. Optical data are not
included for those sources for which only upper limits to the radio
flux density are known.
The "type" column gives the morphological type of the galaxy as given
in the listed references. Generally, a simplified Hubble
classification has been used.
The "B-V" and "U-B" columns give the B-V and U-B colors which are
taken from RC.
The apparent photographic magnitude is given in the "Pmag" column (B(0)
or m(c) or m(H) in decreasing order of preference).
The total corrected apparent magnitude is given in the "Btc" column,
obtained from the B(0) magnitude given in RC or, where B(0) is not
available, from m(c) or m(H). The magnitude thus obtained was
corrected for galactic and internal absorption and then extrapolated
to a total magnitude using the method of Cameron (1971). Data provided
by R.R. Shobbrook (personal communication) were also used.
The "Rvel" column gives the radial velocity (in km/s) of the galaxy
relative to the galactic standard of rest. The circular velocity of
the Sun is taken to be 250 km/s.

History:
* Prepared by H.Andernach, Feb. 1992:
The Compendium of radio observations of normal galaxies was received
in April 1991 from W.Huchtmeier on diskette. The following corrections
were applied:
- a column shift for IC1559 by one column to right
- all blank lines (N=1864) and those containing the string
'CONTINUED' (N=125) were deleted
- morphological types were coded in the original file in only upper
case letters in the "type" column. They were transformed to the
types as published with a special routine and inserted properly for
the '---' strings of the original file (213 cases)
* Made available as table "radbrgals" at the "ADS Catalogue Service"
(CfA, Harvard-Smithsonian Center for Astrophysics, Cambrigde MA)
by Carloyn Stern.
* 07-Nov-2009: references corrected, bibcode added (from H. Andernach)
