Many changes, listed below:

For individual stars:
  * Default number of samplers/steps changed to 5 samplers
    per dimension, 1000 steps per sampler.

  * Minimum replacement/Metropolis-Hastings proposal kernel size
    set to 0.02 in all dimensions, to prevent kernel from ever
    collapsing to zero volume (especially when there are few
    samplers per dimension).

  * Smoothing scale in E(B-V) changed to 0.0125 mag (from 0.02;
    smoothing scale in DM unchanged at 0.2 mag)

For mock catalogs:
  * Unfinished attempt to draw realistic number of stars in
    gen_test_input.py. This is available as a commandline option.

Luminosity function:
  * Luminosity function comes from Parsec. LFs for different
    ages/metallicities are averaged assuming a population
    that is 7 +- 2 Gyr old, with [Fe/H] = -0.5 +- 0.5 dex.
