MakeCatalog’s output measurements/columns can be specified using command-line options (Options). The current measurements in MakeCatalog are those which only produce one final value for each label (for example, its magnitude: a single number). All the different label’s measurements can be written as one column in a final table/catalog that contains other columns for other similar single-number measurements.
In this case, all the different label’s measurements can be written as one column in a final table/catalog that contains other columns for other similar single-number measurements. The majority of this section is devoted to MakeCatalog’s single-valued measurements. However, MakeCatalog can also do measurements that produce more than one value for each label. Currently the only such measurement is generation of spectra from 3D cubes with the --spectrum option and it is discussed in the end of this section.
Command-line options are used to identify which measurements you want in the final catalog(s) and in what order. If any of the options below is called on the command-line or in any of the configuration files, it will be included as a column in the output catalog. The order of the columns is in the same order as the options were seen by MakeCatalog (see Configuration file precedence). Some of the columns apply to both “objects” and “clumps” and some are particular to only one of them (for the definition of “objects” and “clumps”, see Segment). Columns/options that are unique to one catalog (only objects, or only clumps), are explicitly marked with [Objects] or [Clumps] to specify the catalog they will be placed in.
