HAWKI_STEP_COMPUTE_BKG(7) hawki recipes HAWKI_STEP_COMPUTE_BKG(7)

NAME

hawki_step_compute_bkg - (OBSOLETE) Background computing utility

SYNOPSIS

esorex hawki_step_compute_bkg [OPTIONS] FILE.sof

DESCRIPTION

(OBSOLETE) hawki_step_compute_bkg -- hawki background computation utility.

This recipe will create the associated background images for a given set of object images. If there are sky images, these will be used to compute the background, otherwise, the background is computed using a running mean on the object images. An optional mask can be supplied for the running mean.

The files listed in the Set Of Frames (sof-file) must be tagged: obj_basic_cal-file.fits BASIC_CALIBRATED or sky_basic_cal-file.fits SKY_BASIC_CALIBRATED and optionally for object masking: object_mask-file.fits OBJ_MASK offsets.fits OFFSETS_REFINED distortion_x.fits DISTORTION_X distortion_y.fits DISTORTION_Y

OPTIONS

Minimum number of jitter frames to use the running median (int; default: 10). The full name of this option for the EsoRex configuration file is hawki.hawki_step_compute_bkg.nmin_comb [default = 10].
Number of images at both sides of the current ima to use for bkg in running median (int; default: 7). The full name of this option for the EsoRex configuration file is hawki.hawki_step_compute_bkg.nhalf_window [default = 7].
The number of frames with low level to reject (int; default: 2). The full name of this option for the EsoRex configuration file is hawki.hawki_step_compute_bkg.rejlow [default = 2].
The number of frames with high level to reject (int; default: 2). The full name of this option for the EsoRex configuration file is hawki.hawki_step_compute_bkg.rejhigh [default = 2].

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.
