Meeting notes for Sims telecon, Oct 29 2014:

1-866-330-1200
5182287#

Attending: ajc, scott, rahul, michael, kevin, brittany, lynne, debbie, cathy, darko, jim, george

• An introduction to implementing SNe in the simulations (Rahul)
  • slides
  • distribution functions will be simple to start with and then expand
  • do we need to connect with opsim and MAF - yes
  • package SNE code in the photUtils - want to make it agnostic to catalogs so others can use functions outside of catsim
    
  • Rahul  - light curve model goes -20 to +50 day as around maximum light 
• How do we specify angles in the simulations. Should we use a specialized class (e.g afw's angle class) (Scott)
  • there are places in the code where we convert the angles into radians incorrectly (this code isn't used but could cause problems if we have to use it)
    • should we fix these issues, use an angle class, treat ra,dec as special and work to make them consistent?
    • many advantages with an angle class - disadvantage is we can't put this into numpy arrays 
  • problem for MAF as well as catsim
  • George - uniform coordinate transformations and not just angle classes would be useful
    • transform position of the focal plane relative to the optical axis to understand a sensor position 
    • have position of the sensor in the primary mirror system by translating from the sensor coordinate system
    • position sensor relative to raft, raft relative to the mirrors, etc
    • coordinates are known or assumed
  • CameraGeom - can transform within the camera from the focal plane to the pupil but nothing beyond
  • ACTION - can we vectorize an angle class to work with numpy operations, look at AstroPy, and PalPy (Scott)
  • ACTION - how much work to transform afw angles (or build something new) to work in 3D with more coordinate transformations

• Any last minute issues for next week (e.g. is the material ready for Michael)
  • Simon: eups, scons, build system 
  • • starter hack (make opsim installable with the LSST framework)
  • Lynne: agile development, pull requests (stash and git)
  • • starter hack: creating the next sprint for opsim
  • Peter: Using maf
  • • starter hack: use MAF to visualize observations on a single night (and maybe compare an early night to a late night that panics with filter changes)
  • Scott: Using catsim
  • • starter hack: use Catsim to generate images
      
  • Cathy/Kem: Running opsim
  • • starter hack: generating a way to configure large number of runs and persist the configurations
• AOB
  • ACTION - ajc to send round agenda
