An Astropy developer held a workshop at DPS asking for contributions from the plantary science community. Astropy is a Python package for astronomy, and planetary science / Solar System type stuff is notably absent. I wasn't there, but discussed it with Michael Mommert, who was present. So, I'm canvasing for ideas on what to include in a Python package devoted to cometary analysis.

The more specific to comets, the better, but general thoughts on what we would like to see for Solar System type things are good too.

You've hit all of the ones I thought of immediately. Digging deeper for ideas:

  1. Larson-Sekanina filter enhancement
  2. Other enhancement routines (e.g., unsharp mask)
  3. Halley-Marcus dust phase function lookup
  4. Normalization of magnitudes to m(r=1,delta=1,phase=0)
  5. Ephemeris functionality
  6. Visibility plots
  7. Syndyne-synchrone modeling

A few missing items:

Following two are relevant for both photometry module (i.e., calibrated, un-enehanced image) as well as for enhance module (i.e., enhanced image).

  1. polar images (radius vs azimuth)
  2. summed "flux" of radius vs azimuth in polar images (i.e., flux distribution in different position angle wedges)

enhance module:

  1. "azimuthal" should include both "azumuthalaverage" and "azimuthalmedian"
  2. Radially variable spacial filter (RVSF)

Thanks, @Nalin-S . I've added those to the sketch, and reorganized things so that anything that operates on an image is in an image module... for now.

Added to the Wiki, https://github.com/mkelley/cometutils/wiki . I'll ask Mike A for the source of the online tool to make sure we have all the updates.
