obs_LsstSim camera data is not self-consistent

    XMLWordPrintable

    Details

      Description

      The attached scripts use the afw.cameraGeom.Camera provided by obs.lsstSim.LsstSimMapper as well as a camera generated directly from the description/focalplanelayout.txt and description/focalplanelayout.txt from obs_LsstSim to generate pixel coordinates from a catalog of stars. These ought to return identical pixel coordinates. They do not.

      If you run cameraTest.py you will get a catalog that lists the pixel coordinates in the control camera (the camera provided by LsstSimMapper), the pixel coordinates in the test camera, and the difference between the two.

      Note: the scripts use CatSim code, so sims_catUtils will need to be set up.

      Instructions for accessing the CatSim databases are here

            Is this really a SIMs ticket?

            I've tagged this as an obs_lsstSim ticket since I assume the problem is entirely the definition of the internal geometry. Given that obs_lsstSim is deprecated I propose we mark this as WON'T FIX.

            I concur with Tim's recommendation here, since this component is deprecated.
