Usage

Overview

This recipe computes the dark.

The files listed in the Set Of Frames (sof-file) must be tagged either VISIR-dark-image-raw-file.fits IM_CAL_DARK or VISIR-dark-spectro-raw-file.fits SPEC_CAL_DARK

The corresponding four products will each have a FITS card ´HIERARCH ESO PRO CATG´ with values (for imaging) IMG_DARK_AVG IMG_DARK_HOT IMG_DARK_COLD IMG_DARK_DEV
or (for spectroscopy) SPEC_DARK_AVG SPEC_DARK_HOT SPEC_DARK_COLD SPEC_DARK_DEV

Options

--r <str>

Rejected left right bottom and top border (pixel) (str; default: ´50 50 50 50´). The full name of this option for the EsoRex configuration file is visir.visir_img_dark.rej_bord [default = 50 50 50 50].

--hot_t <float>

Hot pixel map threshold (float; default: 10.0). The full name of this option for the EsoRex configuration file is visir.visir_img_dark.hot_threshold [default = 10.0].

--cold_t <float>

Cold pixel map threshold (float; default: 6.0). The full name of this option for the EsoRex configuration file is visir.visir_img_dark.cold_threshold [default = 6.0].

--dev_t <float>

Deviant pixel map threshold (float; default: 5.0). The full name of this option for the EsoRex configuration file is visir.visir_img_dark.dev_threshold [default = 5.0].

--nsamples <int>

Number of samples for Read-Out Noise (RON) computation (int; default: 100). The full name of this option for the EsoRex configuration file is visir.visir_img_dark.nsamples [default = 100].

--hsize <int>

Half size of the window for Read-Out Noise (RON) computation (int; default: 2). The full name of this option for the EsoRex configuration file is visir.visir_img_dark.hsize [default = 2].

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.
