7.3.5.1 MakeCatalog input files

MakeCatalog needs multiple images as input: a values image, one (or two) labeled images and Sky and Sky standard deviation images. The options described in this section allow you to identify them. If you use the default output of NoiseChisel (see NoiseChisel output) you don’t have to worry about any of these options and just give NoiseChisel’s output file to MakeCatalog as described in Invoking MakeCatalog.

-O STR
--objectsfile=STR

The file name of the object labels image, if the image is in another extension of the input file, calling this option is not mandatory, just specify the extension/HDU with the --objectshdu option.

--objectshdu=STR

The HDU/extension of the object labels image. Only pixels with values above zero will be considered. The objects label image has to be an integer data type (see Numeric data types) and only pixels with a value larger than zero will be used. If this extension contains the WCLUMPS keyword with a value of yes, 1, or y (not case sensitive), then MakeCatalog will also build a clumps catalog, see Invoking MakeCatalog.

-C STR
--clumpsfile=STR

Similar to --objlabs but for the labels of the clumps. This is only necessary if the image containing clump labels is not in the input file and the objects image has a WCLUMPS keyword, see --objectshdu.

--clumpshdu=STR

The HDU/extension of the object labels image. Only pixels with values above zero will be considered. The objects label image has to be an integer data type (see Numeric data types) and only pixels with a value larger than zero will be used.

-s STR
--skyfile=STR

File name of an image keeping the Sky value for each pixel.

--skyhdu=STR

The HDU of the Sky value image.

-t STR
--stdfile=STR

File name of image keeping the Sky value standard deviation for each pixel.

--stdhdu=STR

The HDU of the Sky value standard deviation image.
