NAME

       hawki_step_subtract_bkg - (OBSOLETE) Background subtraction utility

SYNOPSIS

       esorex hawki_step_subtract_bkg [OPTIONS] FILE.sof

DESCRIPTION

       (OBSOLETE) hawki_step_subtract_bkg -- hawki background subtraction utility.

       This recipe will subtract the given background to the science images.

       The background can be obtained from the sky or object images using the hawki_util_compute_bkg utility.

       There are two modes of operation: One single background image that it is subtracted to all object images.

       As many background images as objects. A one to one relationship is applied.

       The files listed in the Set Of Frames (sof-file) must be tagged: obj_basic_cal-file.fits BASIC_CALIBRATED
       or background-file.fits BKG_IM

OPTIONS

       Note  that  it  is  possible to create a configuration file containing these options, along with suitable
       default values. Please refer to the details provided by the 'esorex --help' command.
