This function will be well commented regarding inputs, process, and outputs as well as pass errors/warnings if data does not match expected format. This is planned to take 2 weeks, from March 8-March 22nd. This code is to be uploaded to my Github afterward for use in the project.  </p> <p> </p> <p>------</p> <p>Old description:</p> <p>I have developed an FRD/angular misalignment routine to determine how angular misalignment was introduced in images depending on the Cobra fiber position's angular misalignment. This has been tested on pupil images for a test fiber and could reproduce the angular distribution (extracted from sig_tot analysis) observed with 3 angular misalignments and an initial theta and phi position. It is worth investigating whether this is would be a productive analysis to do on the telescope.</p> PIPE2D-623

Angular error extraction from PSFs

Y-axis shows angular misalignment in mrad, while X-axis is in steps of 60 degrees (plot will be updated).</p> <p>Current work on this ticket is available at my Github <a href="https://github.com/bbelland/AngularExtraction." class="external-link" rel="nofollow">https://github.com/bbelland/AngularExtraction</a> I'm modifying some of my previous code that modeled angular misalignment as a function of Cobra position using the angular misalignments extracted from the fiber images. Here I will be assuming that we will not infer angles from FRD data directly from the PSF, which complicates the extraction but the problem should be tractable. </p> Blocks PIPE2D-806 Development Rank 0|zzst9o:zw Sprint 2DDRP-2021 A 2DDRP-2021 A 2 2DDRP-2021 A3 2DDRP-2021 A 4 2DDRP-2021 A5 2DDRP-2021 A 6 2DDRP-2021 A 7 2DDRP-2021 A 8 Story Points 4.0
