True three port integrating sphere handling. Before, there were three ports but one always had to be empty. Now the transmission sphere can have a sample in one port, the detector in another, and a reflectance standard in the third port (opposite the sample port. Before the third port needed to be empty or to have a cap that had the same reflectivity as the sphere walls.

The python program iadplus continues to improve its generated graphs. The new plot is a graph of MR vs. MT and shows where all physically possible points lie for the given set of sphere parameters. Points that fail to converge are plotted and it is easy to see why this might be the case.

v3.16.1 (25 Mar 2024)

  • clarify and revise single sphere effects
  • avoid MC for failed 1 parameter searches
  • change 'empty' -> 'entrance' or 'empty' -> 'third' as appropriate
  • enable constraints in rxt files
  • fix command line regression of constraints
  • improve -x 2 debugging for grid generation
  • improve Valid_Grid
  • add -J to generate grid for plotting
  • improvements to iadplus

v3.16.0 (16 Mar 2024)

  • flexible columns input files!
  • add -w and -W command line options
  • include MC lost light in -z calculations
  • include MC lost light in 1 parameter searches
  • better support for overwriting r&t file data from command-line
  • first version of python wrapper iadplus
  • add more simple checks for bad r & t values
