Usage

Overview

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

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.
