esorex hawki_step_subtract_bkg [OPTIONS] FILE.sof
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
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.
