visir_util_clip - Kappa-sigma clipping of outliers for each pixel

VISIR_UTIL_CLIP(7) visir recipes VISIR_UTIL_CLIP(7)

NAME

visir_util_clip - Kappa-sigma clipping of outliers for each pixel
 

SYNOPSIS

esorex visir_util_clip [OPTIONS] FILE.sof
 

DESCRIPTION

The files listed in the Set Of Frames (sof-file) must be tagged pair-wise: VISIR-raw-file.fits RAW VISIR-bpm-file.fits BPM
 
The product(s) will have a FITS card ´HIERARCH ESO PRO CATG´ with a value of: BPM The outliers are marked as rejected in the matching bad pixel map.
 

OPTIONS

--keepfrac <float>
The fraction of pixels to keep for the initialmedian (float; default: 0.9). The full name of this option for the EsoRex configuration file is visir.visir_util_clip.keepfrac [default = 0.9].
--kappa <float>
Clip outside + or - kappa * sigma (the standard deviation) (float; default: 5.0). The full name of this option for the EsoRex configuration file is visir.visir_util_clip.kappa [default = 5.0].
--maxite <long>
Max number of kappa-sigma clipping iterations (long; default: 3). The full name of this option for the EsoRex configuration file is visir.visir_util_clip.maxite [default = 3].
--shift-beams <bool>
Account for movements of the object defined in CRPIX[12] (bool; default: True). The full name of this option for the EsoRex configuration file is visir.visir_util_clip.shift-beams [default = True].
--error-source <str>
Defines the way errors are generated: img-stdev: stdev of image timeseries: stdev of each pixel over the time axis of the cube none: no error generation (str; default: ´img-stdev´). The full name of this option for the EsoRex configuration file is visir.visir_util_clip.error-source [default = img-stdev].
--error-out-type <str>
Output clipped error as error, variance, weight or none (str; default: ´error´). The full name of this option for the EsoRex configuration file is visir.visir_util_clip.error-out-type [default = error].
--badimage <float>
If percentage of clipped pixels above this value the whole image is considered bad (float; default: 0.2). The full name of this option for the EsoRex configuration file is visir.visir_util_clip.badimage [default = 0.2].
 
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.
