visir_util_convert_weight - Conversion between different weight maps
esorex visir_util_convert_weight [OPTIONS] FILE.sof
The files listed in the Set Of Frames (sof-file) must be tagged: VISIR-weight-map.fits WEIGHT_MAP or VISIR-error-map.fits ERROR_MAP or VISIR-variance-map.fits VARIANCE_MAP VISIR-bpm-file.fits BPM (optional) The relation between an error e, a weight w and a variance v is: e = sqrt(v) = 1/sqrt(w). Depending on the setting of the boolean recipe parameters each input file will cause the following product(s) to be created (each with a FITS card ´HIERARCH ESO PRO CATG´ with the specified value) ERROR_MAP: An error map, requires input v >= 0, w > 0 WEIGHT_MAP: A weight map, requires input e > 0, v > 0 VARIANCE_MAP: A variance map, requires input e >= 0, w > 0 If for a given input the identical output is specified, the data unit(s) may still change according to the provided bad pixel map In a weight map product any bad pixel is set to 0. In a variance or error map product any bad pixel is set to the value specified by the relevant recipe option.
--error <bool> Convert to error (bool; default: True). The full name of this option for the EsoRex configuration file is visir.visir_util_convert_weight.error [default = True]. --weight <bool> Convert to weight. Bad pixels are seto to 0 (bool; default: False). The full name of this option for the EsoRex configuration file is visir.visir_util_convert_weight.weight [default = False]. --variance <bool> Convert to variance. Bad pixels are seto to 0 (bool; default: False). The full name of this option for the EsoRex configuration file is visir.visir_util_convert_weight.variance [default = False]. --bad_value <float> The value to use for any bad pixel in an error or variance map (float; default: 3.4028234663852886e+38). The full name of this option for the EsoRex configuration file is visir.visir_util_convert_weight.bad_value [default = 3.4028234663852886e+38]. --bad_flag <bool> The value used to flag a bad pixel in an input bad pixel map. True: 1. False: 0. (bool; default: True). The full name of this option for the EsoRex configuration file is visir.visir_util_convert_weight.bad_flag [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.
The full documentation for the visir pipeline can be downloaded as a PDF file using the following URL: ftp://ftp.eso.org/pub/dfs/pipelines/visir/visir-pipeline-manual-1.4.pdf An overview over the existing ESO pipelines can be found on the web page https://www.eso.org/sci/software/pipelines/. Basic documentation about the EsoRex program can be found at the esorex (1) man page. It is possible to call the pipelines from python using the python-cpl package. See https://packages.python.org/python-cpl/index.html for further information. The other recipes of the visir pipeline are visir_img_dark(7), visir_img_ff(7), visir_img_reduce(7), visir_img_trans(7), visir_old_img_combine(7), visir_old_img_phot(7), visir_old_spc_obs(7), visir_old_spc_obs_ech(7), visir_old_spc_phot(7), visir_old_spc_phot_ech(7), visir_old_spc_wcal(7), visir_old_spc_wcal_ech(7), visir_old_util_destripe(7), visir_spc_reduce(7), visir_util_apply_calib(7), visir_util_clip(7), visir_util_detect_shift(7), visir_util_img_std_cat(7), visir_util_join(7), visir_util_qc(7), visir_util_repack(7), visir_util_run_swarp(7), visir_util_spc_std_cat(7), visir_util_spc_txt2fits(7), visir_util_undistort(7)
