Goals

  • Touch base after a majority of the group has been traveling.
    • Current status of tests
    • Plans to get first/preliminary results


Discussion items

Paul has handed off a set of runs to be analyzed.

  • CIHSC (single frame measurements)
  • Compression is occurring on the fly for the single-epoch (individual images) prior to building the mosaic
  • Runs occur over a single patch (two filters) with q=4–128.
  • Bob Armstrong will provide initial guess at which parameters should be tested with respect to shape measuement
  • Sophie Reed will make catalog comparisons to show the degree results change with respect to quantization factor used for compression

Should have initial results prior to the next meeting (Nov 27).  

We should expect at that time to critically assess the tests we are making and how they are implemented in the pipeline.

  • current top of my list (we should consider only compressing once the coadd/patch images are constructed)
  • will need to look at performance of measurement on single frames (compressed and uncompressed).
