RASSGB - RASS/Green Bank Catalog |
HEASARC Archive |
The published version of this catalog comprised two main tables, Table 2 and Table 3. Table 2 gave the 5-GHz high resolution radio source properties for the 1861 Rosat/Green Bank sources for which subarcsecond positions and core radio flux densities had been obtained, while Table 3 gave the 5-GHz radio source properties for the 436 Rosat/Green Bank sources for which only low resolution data were obtained. A table of the 83 Rosat/Green Bank sources for which no radio source greater than 5 sigma was observed in the follow-up VLA observations (Table 4 in the paper) is not included in the present HEASARC RASSGB Catalog but is available in our anonymous ftp area at:
ftp://legacy.gsfc.nasa.gov/heasarc/dbase/misc_files/rassgb/
Name
The name of the source in the RASS/Green Bank Catalog. Notice that
this is the designation recommended by the `Dictionary of Nomenclature of
Celestial Objects'. Letter suffixes 'A', 'B', 'C', etc., are used to
denote multiple radio sources found in a particular field.
RA
The right ascension of the radio source in the selected equinox.
The data in the published catalog were given at the J2000 equinox, notice,
and this equinox should be selected if the user desires the highest positional
accuracy in the HEASARC database version. Sources for which high-resolution
radio data are available (ie., objects in Table 2 of the paper, designated
by resolution = 'HIGH' in this database) had RAs that were given to the
hundredth (second decimal place) in the unit of seconds of time, while sources
for which only low-resolution radio data are available (ie., objects in Table 3
of the paper, designated by resolution = 'LOW' in this database) had RAs that
were given to the tenth (first decimal place) in the unit of seconds of time.
Dec
The declination of the radio source in the selected equinox.

radio data are available (ie., objects in Table 2 of the paper, designated
by resolution = 'HIGH' in this database) had declinations that were given to the
tenth (first decimal place) in the unit of arcseconds, while sources for which
only low-resolution radio data are available (ie., objects in Table 3 of the
paper, designated by resolution = 'LOW' in this database) had declinations
were given to the nearest arcsecond.
LII
The galactic longitude of the radio source.
BII
The galactic latitude of the radio source.
Epoch_Code
A code for the epoch of the VLA observation (Table 1 in
published paper) as follows:
Observing Date Code Config Tobs Beam Oct 19 1992 A A 1.0 0.4 May 7 1994 B AnB 0.8 1.3 Sept 15 1994 C BnC 3.2 4.0 Sept 28 1995 D AnB 4.2 1.2 Oct 3 1992 E D 1.0 29. Config: VLA Configuration. Tobs: Average Observation time per field in minutes. Beam: Typical synthesized beam size in arcseconds.
SNR
The signal to noise (S/N) ratio of the detected radio source.
Flux_6_cm
The corrected 5-GHz core VLA flux density in milliJanskies
(mJy) calculated from the observed flux density according to equations (1)
to (3) of Laurent-Muehleisen et al. (1997, A&AS, 122, 235).
Total_Flux_6_cm
The total 5-GHz Green Bank flux density in milliJanskies
(mJy) taken from the Greenbank 5-GHz Radio Survey (Gregory et al. 1996,
ApJS, 103, 427), or from the reanalysis of the Green Bank Survey images.
Total_Flux_6_cm_Error
The error in the total Green Bank flux density,
in milliJanskies, if the source appeared in Gregory et al. 1996,
ApJS, 103, 427.

Resolution
A HEASARC-created parameter that is set to `High' for sources
taken from Table 2 of the published catalog and to `Low' for sources taken
from table 3. Thus, sources for which high (sub-arcsecond) spatial resolution
radio data are available are designated by resolution = 'HIGH', while sources
for which only low spatial resolution radio data are available are designated
by resolution = 'LOW'.
