Description

hawki_twilight_flat_combine -- HAWKI twilight flat combine recipe. Combine a list of twilight flat frames into a mean frame. Optionally compare the output frame to a master twilight flat frame The program accepts the following files in the SOF: Tag Description FLAT_TWILIGHT A list of raw twilight flat images MASTER_DARK A master dark frame REFERENCE_TWILIGHT_FLAT Optional reference twilight flat frame MASTER_BPM Optional master bad pixel map or MASTER_CONF Optional master confidence map If no reference twilight flat is made available, then no comparison will be done. This means there will be no output ratio image. If either a masterbad pixel mask or a master confidence map is specified, this will be usedto help mask out bad pixels

Name

hawki_twilight_flat_combine - HAWKI twilight combination recipe

Options

--lthr<float> Low rejection threshold for underexpsed images (float; default: 4000.0). The full name of this option for the EsoRex configuration file is hawki.hawki_twilight_flat_combine.lthr [default = 4000.0]. --hthr<float> High rejection threshold for overexposed images (float; default: 30000.0). The full name of this option for the EsoRex configuration file is hawki.hawki_twilight_flat_combine.hthr [default = 30000.0]. --combtype<str> Combination algorithm (str; default: ´median´). The full name of this option for the EsoRex configuration file is hawki.hawki_twilight_flat_combine.combtype [default = median]. --scaletype<str> Scaling algorithm (str; default: ´multiplicative´). The full name of this option for the EsoRex configuration file is hawki.hawki_twilight_flat_combine.scaletype [default = multiplicative]. --xrej<bool> True if using extra rejection cycle (bool; default: True). The full name of this option for the EsoRex configuration file is hawki.hawki_twilight_flat_combine.xrej [default = True]. --thresh<float> Rejection threshold in sigma above background (float; default: 5.0). The full name of this option for the EsoRex configuration file is hawki.hawki_twilight_flat_combine.thresh [default = 5.0]. --ncells<int> Number of cells for data channel stats (int; default: 8). The full name of this option for the EsoRex configuration file is hawki.hawki_twilight_flat_combine.ncells [default = 8]. --prettynames<bool> Use pretty output file names? (bool; default: False). The full name of this option for the EsoRex configuration file is hawki.hawki_twilight_flat_combine.prettynames [default = False]. 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.

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.
