Making cutouts from local FITS images
Table of contents
Single cutouts
The simplest cutout command is
everystamp cutout --image <fits image> --ra <ra> --dec <dec> --size <size>
where the position and size are in degrees. The option --cutout-mode option can be set to either astropy to use its Cutout2D, or fast to try and simply slice a subarray out of the main image. The latter can be faster for large images.
Batch cutouts from a catalogue
If you have a catalogue with RA and DEC columns, EveryStamp can make cutouts of all those sources automatically by specifcying the catalogue through --from_catalogue.
everystamp cutout --image <fits image> --ra <ra> --dec <dec> --size <size> --from_catalogue <mycatalogue>
