Data collections and computer codes

hosted by PSR Helsinki group. Note, we are currently streamlining the codes and the way they are distributed. While this is ongoing, there is a note 'DEPRECATED' with old versions which will be updated and repackaged.

  • Gaussian spheres, a part of the SIRIS4 framework, generates Gaussian random sphere geometries
  • Single-particle geometric optics with diffuse scatterers using Gaussian particles, part of the SIRIS4 framework
  • Computer codes for H,G1,G2 and H,G12 photometric systems
  • absMie, a Fortran conversion of the Mathematica Mie code for sphere in absorbing medium by Sudiarta
  • Numerical scattering law for solar system bodies
  • AAMS database of asteroid photometric parameters, i.e. absolute magnitudes and phase curve slope parameters
  • DEPRECATED: SIRIS, package for generation of sample Gaussian spheres and for the computation of light scattering by Gaussian particles and arbitrary polyhedral particles in the ray optics approximation
  • DEPRECATED: SIRIS version 4.2 for core-mantle geometry and inhomogenous waves in absorbing media
  • DEPRECATED: FaSTMM, a fast superposition T-matrix method code for exact scattering properties of a collection of spherical particles
  • DEPRECATED: RT-CB for Radiative Transfer with Coherent Backscattering effects
  • DEPRECATED: R2T2 for Radiative Transfer with Reciprocal Transactions
  • Asteroid Photometric Catalogue for asteroid lightcurves and asteroid phase curve analyzer (DECOMMISSIONED IN MARCH 2017)
