| Description |
|
The FITS working group has decided that the science detectors should get a slit hole id vs lambda WCS. Rough wavelength solution is fine. Not obvious which `pfsDetectorMap` to use. |

Whatever routine implements this should return both the WCS cards and the 'DISPERSR', 'WAVELEN', 'WAV-MAX', and 'WAV-MIN' cards as specified in I will make a pfs_utils.getSpsWcs(module, arm) routine to return the We still need information on how well we need to do for the WCS: is linear in lambda, fiberId good enough to put in now? Can/should someone (not me) make a better map? |

Further discussion yielded the following agreement: we will add a simple linear WCS, mapping FITS pixel (1,1) to pixel (0,0). We will not attempt anything with wavelengths or fiber IDs. |
