kmos_extract_spec7

Usage

Overview

This recipe extracts a spectrum from a datacube. The datacube is with or without noise). The output will be a similarly formatted FITS file.

Input files:

DO KMOS
category Type Explanation Required #Frames
-------- ----- ----------- -------- -------
<none or any> F3I The datacubes Y 1
<none or any> F2I The mask N 0,1

EXTRACT_SPEC F1I Extracted spectrum
EXTRACT_SPEC_MASK F2I (optional, if --save_mask=true and
--mask_method=´optimal´: The calculated mask)

Options

--mask_method <str>

Method used : mask, integrated or optimal (str; default: ´integrated´). The full name of this option for the EsoRex configuration file is kmos.kmos_extract_spec.mask_method [default = integrated].

--centre <str>

The centre of the circular mask (pixel) (str; default: ´7.5,7.5´). The full name of this option for the EsoRex configuration file is kmos.kmos_extract_spec.centre [default = 7.5,7.5].

--radius <float>

The radius of the circular mask (pixel) (float; default: 3.0). The full name of this option for the EsoRex configuration file is kmos.kmos_extract_spec.radius [default = 3.0].

--save_mask <bool>

Flag to save the mask (bool; default: False). The full name of this option for the EsoRex configuration file is kmos.kmos_extract_spec.save_mask [default = False].

--cmethod <str>

Apply "average", "median", "sum", "min_max." or "ksigma". (str; default: ´ksigma´). The full name of this option for the EsoRex configuration file is kmos.kmos_extract_spec.cmethod [default = ksigma].

--cpos_rej <float>

The positive rejection threshold for kappa-sigma-clipping (sigma). (float; default: 3.0). The full name of this option for the EsoRex configuration file is kmos.kmos_extract_spec.cpos_rej [default = 3.0].

--cneg_rej <float>

The negative rejection threshold for kappa-sigma-clipping (sigma). (float; default: 3.0). The full name of this option for the EsoRex configuration file is kmos.kmos_extract_spec.cneg_rej [default = 3.0].

--citer <int>

The number of iterations for kappa-sigma-clipping. (int; default: 3). The full name of this option for the EsoRex configuration file is kmos.kmos_extract_spec.citer [default = 3].

--cmax <int>

The number of maximum pixel values to clip with min/max-clipping. (int; default: 1). The full name of this option for the EsoRex configuration file is kmos.kmos_extract_spec.cmax [default = 1].

--cmin <int>

The number of minimum pixel values to clip with min/max-clipping. (int; default: 1). The full name of this option for the EsoRex configuration file is kmos.kmos_extract_spec.cmin [default = 1].

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.
