catalog_robust.fits

The robust version of the 1.3mm dust continuum catalog. Generated by a pruned dendrogram, keeping only leaves with a signal to RMS of at least 6\sigma and a mean signal to RMS of at least 2\sigma. FITS file. Key Descriptions: INDEX: number matching leaf mask value. AREA_ELLIPSE: the area of ellipse extracted from astrodendro moment analysis. AREA_EXACT: exact area of leaf. FLUX_INTEGRATED: integrated flux over entire leaf. MAJOR_SIGMA: major axis sigma extracted by astrodendro moment analysis. MINOR_SIGMA: minor axis sigma extracted by astrodendro moment analysis. POSITION_ANGLE: position angle extracted by astrodendro moment analysis. RADIUS: radius extracted by astrodendro moment analysis. GLON: Galactic Longitude of leaf center. GLAT: Galactic Latitude of leaf center. R_EFF: effective radius for leaf, calculated as sqrt(leaf area / pi). FLUX_INTEGRATED_BGSUB: background subtracted integrated flux. NOISE: estimate of the local noice in Jr/Sr. MIN_CONT_FLUX: minimum continuum flux, in Jr/Sr. MEAN_CONT_FLUX: mean continuum flux in Jr/Sr. PEAK_CONT_FLUX: peak continuum flux in Jr/Sr. NPIX: number of image pixels associated with the leaf. DUSTTEMPERATURE: the Herschel derived dust temperature in K at 36'' resolution. HERSCHEL_COLUMN: Herschel derived column density at 36'' resolution in 1/cm2. MASS: leaf mass in msun . SMA_COLUMN: column density derived from SMA dust continuum in 1/cm2. R_EFF_PC: leaf effective radius (as above) in parsecs, converted using distance from Gravity Collaboration 2019). SIGMA: mean surface density of leaf in g/cm2 n: mean volume number density of leaf in 1/cm3. RHO: volume number density in kg/cm3 TFF: freefall time of leaf in years GLON_0: Galactic longitude with negative values for l<0. MASS_BGSUB: background subtracted mass in msun. suspicious: flag for leaves within 15 pixels of map edge, maybe suspicious due to edge artifacts from primary beam correction. leaf_ID: unique ID for leaf, constructed from parent cloud ID and alphabetized in order of decreasing leaf mass. MASK_NUM: mask number of the cloud from the cloud mask. MASS_UNC: uncertainty in leaf mass (msun). N_UNC: uncertainty in leaf SMA column density (1/cm2). n_UNC: uncertainty in leaf volume number density (1/cm3). TFF_UNC: uncertainty in leaf freefall time (years). RHO_UNC: uncertainty in leaf volume mass density (kg/cm3). MASS_BGSUB_UNC: uncertainty in leaf background subtracted mass (msun).
