NAME¶

hawki_detector_noise - HAWKI detector noise recipe

SYNOPSIS¶

esorex hawki_detector_noise [OPTIONS] FILE.sof

DESCRIPTION¶

hawki_detector_noise -- HAWKI recipe to find readnoise and gain.

Compute the readnoise and gain for the hawki detectors using two dark frames and two flat field frames. Both must have been exposed with NDIT=1 The program accepts the following files in the SOF:

Tag Description

DARK A list of raw dark images
FLAT_TWILIGHT A list of raw flat images
MASTER_BPM Optional master bad pixel mask or
MASTER_CONF Optional master confidence map If a master bad pixel mask or confidence map is included then thebad pixels will be flagged during the statistical analysis

OPTIONS¶

--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_detector_noise.thresh [default = 5.0].

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. See https://packages.python.org/python-cpl/index.html for further information.
