The input files must be tagged: distortion\_field.fits DISTOR\_OBS sky\_distortion.fits DISTOR\_SKY flat-file.fits FLAT\_IM (optional) dark-file.fits DARK\_IM (optional) bpm-file.fits BPM (optional) The recipe creates as an output: hawki\_cal\_distortion\_distx.fits (DISTORTION\_X) hawki\_cal\_distortion\_disty.fits (DISTORTION\_Y) The recipe performs the following steps: -Basic calibration of astrometry fields -Autocalibration of distortion, using method in A&A 454,1029 (2006) Return code: esorex exits with an error code of 0 if the recipe completes successfully or 1 otherwise ## OPTIONS - **--sigma\_det** *\* detection level (float; default: 6.0). The full name of this option for the EsoRex configuration file is **hawki.hawki\_cal\_distortion.sigma\_det** \[default = *6.0*\]. - **--grid\_points** *\* number of points in distortion grid (int; default: 9). The full name of this option for the EsoRex configuration file is **hawki.hawki\_cal\_distortion.grid\_points** \[default = *9*\]. - **--borders** *\* number of pixels to trim at the borders (int; default: 6). The full name of this option for the EsoRex configuration file is **hawki.hawki\_cal\_distortion.borders** \[default = *6*\]. - **--subtract\_linear** *\* Subtract a linear term to the solution (bool; default: True). The full name of this option for the EsoRex configuration file is **hawki.hawki\_cal\_distortion.subtract\_linear** \[default = *True*\]. 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. ## SEE ALSO The full documentation for the hawki pipeline can be downloaded as a PDF file using the following URL: - **ftp://ftp.eso.org/pub/dfs/pipelines/hawki/hawki-pipeline-manual-2.4.11.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.
