Hi Britton et al.  Congrats on the release.  The subject line caught my attention, but if I look at the project page, it is hard for me to understand what this package does.  I was curious if anything here would be useful for the work I do.  Can I suggest that maybe a sentence or two be added to the top of the README to explain what sorts of analysis this enables?

Best,

Mike

Greetings!

yt_astro_analysis version 1.1 is released!

yt_astro_analysis is an extension of yt for astrophysical analysis. This is the first stable release of yt_astro_analysis to be compatible with yt version 4.0 and later.

New Features

• The HaloCatalog has been significantly refactored (#58, #62) with the following additional improvements:
  • the interface to the Rockstar halo finder is now compatible with the latest version of Rockstar Galaxies #55
  • all halo finders now support being run with time-series of datasets
  • halo particle ids now savable with FoF and HOP halo finders #52
  • looping over halos is done with io chunks instead of ds.all_data for a significant speedup and reduction in memory
  • Allow more flexibility for specifying rockstar particle mass #84
  • Add restart option for rockstar #82
  • Adding an outer_radius parameter to the iterative COM callback #34
• Remove the sunyaev_zeldovich analysis module. This is now pyxsim. #79

• only access particle_type field in rockstar if it exists and is needed #111
• fix light cone projections with weight fields #37
• Fix HaloCatalog progress bar #40
• clarify rockstar error message about using the wrong number of MPI processes #42, #113
• check derived_field_list for base fields #43
• allow cosmology splice from a single dataset #49
• Fix iterator #68
• Support new config file format #65
• Enable circleci testing #44
