Description of the columns for the GRS cloud and clump catalogs.

JMR - March 2009

The columns for the cloud catalog are as follows: 
(1) the molecular cloud name, designated as GRSMC (for GRS Molecular Cloud) 
followed by the Galactic longitude and latitude (l and b) coordinates of
the peak of the emission in degrees, e.g. GRSMC G053.59+00.04; (2), (3) and 
(4) the Galactic coordinates (l and b) and velocity (Vlsr) of the peak voxel 
of the emission; (5) the velocity FWHM defined as 2.35 times the velocity 
dispersion (Delta V); (6) main beam temperature of the peak voxel (Tmb); 
(7) and (8) the Galactic coordinates (l and b) of the centroid of the integrated
intensity image; (9) and (10) the semimajor and semiminor axes (a
and b), determined from the elliptical Gaussian fit to the integrated
intensity image; (11) position angle of the fitted ellipse, measured
counter-clockwise from the positive longitude axis (PA); (12) the
projected two-dimensional area (A); (13) the average main beam
temperature of the cloud, defined as the average main beam temperature
of all the voxels (Tav); (14) the peak integrated intensity
(Ipeak); (15) the total 13CO integrated intensity
(Itotal); (16) the peak H2 column density N(H2); and (17)
a flag denoting if the cloud lies on one of the survey boundaries
('X', 'Y' or 'V' indicate that the cloud lies on the boundary in
Galactic longitude, Galactic latitude or velocity, respectively.)

The columns for the clump catalog are as follows: 
(1) the molecular cloud name (from the cloud catalog); (2) the clump
number, e.g. c1, c2, c3, etc; (3), (4) and (5) the Galactic
coordinates (l and b) and velocity (Vlsr) of the peak voxel of
the emission; (6), (7) and (8) the FWHM extent in longitude, latitude
and velocity (Delta l, Delta b, and Delta,V); (9) the
main beam temperature of the peak voxel (Tmb); (10) the projected
two-dimensional area (A); (11) the peak integrated intensity
(Ipeak); (12) the total 13CO integrated intensity
(Itotal); (13) the peak H2 column density (N(H2)); and
(14) a flag denoting if the clump lies on a boundary.
