Usage

Overview

This recipe is used to create a master sky flat field from a set of raw sky flat fields. The master sky flat field is the dataset used for the flat field correction of scientific data.

Input files:

DO category: Type: Explanation: Required:
IMG_SKY_FLAT Raw Sky flat exposure Y
MASTER_BIAS Calib Master bias Y
MASTER_DARK Calib Master dark .

IMG_MASTER_SCREEN_FLAT Calib Master screen flat .

CCD_TABLE Calib Bad pixel table .

Output files:

DO category: Data type: Explanation:
IMG_MASTER_SKY_FLAT FITS image Master sky flat field

If a master screen flat is specified, the input sky flat exposures are flat-fielded with it, and then just used to determine the large scale trends of the instrument response; the result is then multiplied by the master screen flat. A CCD table must be specified in input only if a bad pixel cleaning is requested.

For more details, please refer to the VIMOS Pipeline User´s Guide.

Options

--SmoothBoxSize <int>

Size of running box used for smoothing (int; default: 7). The full name of this option for the EsoRex configuration file is vimos.Parameters.smooth.boxsize [default = 7].

--SmoothMethod <str>

Smooth method for image trends removal (str; default: ´Median´). The full name of this option for the EsoRex configuration file is vimos.Parameters.smooth.method [default = Median].

--AllowSingleFrames <bool>

Frame combination method is ignored. (bool; default: True). The full name of this option for the EsoRex configuration file is vimos.Parameters.stacking.singleframes [default = True].

--StackMethod <str>

Frames combination method (str; default: ´Median´). The full name of this option for the EsoRex configuration file is vimos.Parameters.stacking.method [default = Median].

--KSigmaLow <float>

Low threshold for K-sigma clipping method (float; default: 5.0). The full name of this option for the EsoRex configuration file is vimos.Parameters.stacking.ksigma.low [default = 5.0].

--KSigmaHigh <float>

High threshold for K-sigma clipping method (float; default: 5.0). The full name of this option for the EsoRex configuration file is vimos.Parameters.stacking.ksigma.high [default = 5.0].

--MinRejection <int>

Number of lowest rejected values for rejection method (int; default: 1). The full name of this option for the EsoRex configuration file is vimos.Parameters.minmax.minimum [default = 1].

--MaxRejection <int>

Number of highest rejected values for rejection method (int; default: 1). The full name of this option for the EsoRex configuration file is vimos.Parameters.minmax.maximum [default = 1].

--BiasMethod <str>

Bias removal method. (str; default: ´Zmaster´). The full name of this option for the EsoRex configuration file is vimos.Parameters.bias.removing.method [default = Zmaster].

--CleanBadPixel <bool>

Bad pixel correction on master flat (bool; default: False). The full name of this option for the EsoRex configuration file is vimos.Parameters.badpixel.clean [default = False].

--CleanCosmic <bool>

Cosmic ray events cleaning from raw flats (bool; default: False). The full name of this option for the EsoRex configuration file is vimos.Parameters.cosmics.clean [default = False].

--CosmicThreshold <float>

Threshold to identify cosmic rays candidates. (float; default: 4.0). The full name of this option for the EsoRex configuration file is vimos.Parameters.cosmics.threshold [default = 4.0].

--CosmicRatio <float>

Min ratio between peak and nearby pixels for a cosmic ray. (float; default: 2.0). The full name of this option for the EsoRex configuration file is vimos.Parameters.cosmics.ratio [default = 2.0].

--ComputeQC <bool>

Compute QC1 parameters. (bool; default: True). The full name of this option for the EsoRex configuration file is vimos.Parameters.quality.enable [default = True].

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.
