To Do List

  • Formatted survey options printout.
  • Use latest fitsio for writing simulation output.
  • Use better 8-char names and add comments to FITS headers.
  • Is the optical PSF making any difference? How much does it slow down simulate?
  • Implement a ‘exposure-time calculator’ to calculate quantities for a profile specified on the command line (idea from Josh Meyers).
  • Include a prior on dilation scale parameter for error estimation?
  • Add ra,dec pointing and WCS to FITS primary HDU written by simulate.
  • More flexible handling of the ra,dec catalog query window (we currently assume the query is centered near the origin).
  • python 2-to-3 migration: from __future__ import absolute_import, division, print_function, unicode_literals
  • Add zscale color gradient and angular scale legend options to display.py
  • Add option to specify display view bounds independently of selected objects.
  • Increase simulated area (from 1 LSST chip) for data products?
  • Add option to add arbitrary fraction of 2*pi to all position angles (for ring tests).

Longer-Term Projects

  • Validate galaxy input catalog quantities against existing datasets.
  • Add stars from some catalog and estimate their contributions to blending statistics.
  • Integrate over survey observing conditions (seeing, sky, ...) using operations simulator output.
  • Test toy deblender performance on simulated images (Josh Myers).
  • Compare sextractor object detection with snr_grp detection threshold (Mandeep Gill).
  • Compare DM pipeline object detection with snr_grp detection threshold.
  • Use PhoSim to generate realistic bright-star templates that could be used in GalSim (Chris Walter).
  • Compare GalSim and PhoSim images generated for the same catalog footprint (Matt Wiesner).
  • Characterize galaxies that look like stars (Alex Abate + Elliott Cheu + Arizona undergrad).
  • Compare CFHTLS predictions with published results (Dominique Boutigny).
  • Compare DES predictions with actual DES imaging.
  • Add survey parameters for HSC to Survey class and compare predictions with actual HSC imaging (Rachel Mandelbaum).
  • Include CatSim SEDs to implement band-dependent bulge/disk ratios and synthesize non-LSST magnitudes.
  • Study dependence of full-depth neff on assumed mean sky noise and seeing.
