Usage

Overview

This recipe is used to create a master screen flat field from a set of raw screen flat fields. The master screen flat field is not used directly in the flat field correction of scientific data, but it is optionally used just in the creation of a master sky flat field by the recipe vmimflatsky.

Input files:

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

CCD_TABLE Calib Bad pixel table .

Output files:

DO category: Data type: Explanation:
IMG_MASTER_SCREEN_FLAT FITS image Master screen flat field
IMG_COMBINED_SCREEN_FLAT FITS image Combined screen flat field

The primary product is the normalised master screen flat field.

A secondary product is the combined screen flat field, that is the result of the combination of all inputs but without any normalisation applied, and is just used for data quality control. 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: ´Average´). The full name of this option for the EsoRex configuration file is vimos.Parameters.stacking.method [default = Average].

--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.
