visir_util_run_swarp - Run swarp program to coadd images.


esorex visir_util_run_swarp [OPTIONS] FILE.sof


WARNING: this recipe is intented to be run in a temporary directory, it does not clean up behind itself The files listed in the Set Of Frames (sof-file) must be tagged: VISIR-chopnod-corrected-file.fits BKG_CORRECTED VISIR-error-map.fits ERROR_MAP It will produce the coaddition of each input frame separately and of all frames together.

The single frame product(s) will have a FITS card ´HIERARCH ESO PRO CATG´ with a value of: COADDED_IMAGE and COADDED_WEIGHT The total coaddition will have the tags COADDED_IMAGE_COMBINED and COADDED_WEIGHT_COMBINED


Output a coadded image for each input file in addition to the complete coaddition. (bool; default: False). The full name of this option for the EsoRex configuration file is visir.visir_util_run_swarp.output-all [default = False].
Additional configuration parameters (str; default: ´NONE´). The full name of this option for the EsoRex configuration file is visir.visir_util_run_swarp.extra_config [default = NONE].
Swarp configure file name. (str; default: ´/usr/share/cpl- plugins/visir-4.4.2/config/visir_default.swarp´). The full name of this option for the EsoRex configuration file is visir.visir_util_run_swarp.config_fname [default = /usr/share/cpl-plugins/visir-4.4.2/config/visir_default.swarp].
Maximum number of swarp processes that can be spawned simultaneously. (int; default: -1). The full name of this option for the EsoRex configuration file is visir.visir_util_run_swarp.nprocs [default = -1].

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.
