KPM Measurement: Residual PSF Ellipticity Correlations (TE1), FY15

    Details

    • Type: Epic
    • Status: Done
    • Resolution: Done
    • Fix Version/s: None
    • Component/s: None

    • Epic Name:
      KPM: TE1, FY15
    • WBS:
      02C.04
    • Team:
      Data Release Production
    • Cycle:
      Summer 2015

      Description

      This will be measured on precursor data (almost certainly from HSC, via DM-2380) using the following procedure:

      • Run visit-level processing (i.e. ProcessCcdTask, probably via the new HSC driver ported on DM-3368).
      • Compute the residual ellipticity correlation function separately in each visit. Bob Armstrong has code we can probably use for this (and will be at LSST2015 to help). The stile project (https://github.com/msimet/Stile) may be another solution (and perhaps a better long-term one).
      • Compute the median correlation function (at separation bins) over multiple visits.

      This will be done in whichever of r or i band has better public HSC data.

      The same measurement procedure will be used for TE2 (DLP-308) in S15 (DM-3047).

            Description This will be measured on precursor data (almost certainly from HSC, via DM-2380) using the following procedure:
             - Run visit-level processing (i.e. {{ProcessCcdTask}}, probably via the new HSC driver ported on DM-3368). This must include the HSM moments code (DM-3384), which are not enabled by default.
             - Compute the residual ellipticity correlation function separately in each visit. Bob Armstrong has code we can probably use for this (and will be at LSST2015 to help). The _stile_ project (https://github.com/msimet/Stile) may be another solution (and perhaps a better long-term one).
