muse_exp_align - Create a coordinate offset table to be used to align exposures

MUSE_EXP_ALIGN(7) muse recipes MUSE_EXP_ALIGN(7)

NAME

muse_exp_align - Create a coordinate offset table to be used to align exposures during exposure combination.
 

SYNOPSIS

esorex muse_exp_align [OPTIONS] FILE.sof
 

DESCRIPTION

Compute the coordinate offset for each input field-of-view image with respect to a reference. The created list of coordinate offsets can then be used in muse_exp_combine as the field coordinate offsets to properly align the exposures during their combination.
 

OPTIONS

--rsearch <str>
Search radius (in arcsec) for each iteration of the offset computation. (str; default: ´30.,4.,2.,0.8´). The full name of this option for the EsoRex configuration file is muse.muse_exp_align.rsearch [default = 30.,4.,2.,0.8].
--nbins <long>
Number of bins to use for 2D histogram on the first iteration of the offset computation. (long; default: 60). The full name of this option for the EsoRex configuration file is muse.muse_exp_align.nbins [default = 60].
--weight <bool>
Use weighting. (bool; default: True). The full name of this option for the EsoRex configuration file is muse.muse_exp_align.weight [default = True].
--fwhm <float>
FWHM in pixels of the convolution filter. (float; default: 5.0). The full name of this option for the EsoRex configuration file is muse.muse_exp_align.fwhm [default = 5.0].
--threshold <float>
Initial intensity threshold for detecting point sources in sigma above background RMS. (float; default: 15.0). The full name of this option for the EsoRex configuration file is muse.muse_exp_align.threshold [default = 15.0].
--step <float>
Increment/decrement of the threshold value in subsequent iterations. (float; default: 0.5). The full name of this option for the EsoRex configuration file is muse.muse_exp_align.step [default = 0.5].
--iterations <long>
Maximum number of iterations used for detecting sources. (long; default: 100000). The full name of this option for the EsoRex configuration file is muse.muse_exp_align.iterations [default = 100000].
--srcmin <long>
Minimum number of sources which must be found. (long; default: 5). The full name of this option for the EsoRex configuration file is muse.muse_exp_align.srcmin [default = 5].
--srcmax <long>
Maximum number of sources which may be found. (long; default: 80). The full name of this option for the EsoRex configuration file is muse.muse_exp_align.srcmax [default = 80].
--roundmin <float>
Lower limit of the allowed point-source roundness. (float; default: -1.0). The full name of this option for the EsoRex configuration file is muse.muse_exp_align.roundmin [default = -1.0].
--roundmax <float>
Upper limit of the allowed point-source roundness. (float; default: 1.0). The full name of this option for the EsoRex configuration file is muse.muse_exp_align.roundmax [default = 1.0].
--sharpmin <float>
Lower limit of the allowed point-source sharpness. (float; default: 0.2). The full name of this option for the EsoRex configuration file is muse.muse_exp_align.sharpmin [default = 0.2].
--sharpmax <float>
Upper limit of the allowed point-source sharpness. (float; default: 1.0). The full name of this option for the EsoRex configuration file is muse.muse_exp_align.sharpmax [default = 1.0].
 
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.
