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.

An overview over the existing ESO pipelines can be found on the web page http://www.eso.org/sci/software/pipelines/.
Basic documentation about the EsoRex program can be found at the esorex (1) man page.
It is possible to call the pipelines from python using the python-cpl package. See http://packages.python.org/python-cpl/index.html for further information.
