Randomly sampled coefficients for synchrotron radiative transfer in the Stokes basis, power law model, computed by rimphony, for consumption by neurosynchro

This directory contains a training set of 22 million randomly-sampled radiative transfer coefficients generated by rimphony, suitable for use with the neurosynchro package. These coefficients can be used for numerical radiative transfer of synchrotron emission in the Stokes basis with a package such as grtrans.

In this particular dataset, coefficients were computed using a model of a power law electron distribution isotropic in pitch angle. The input parameters, which were sampled randomly in a three-dimensional space, are:

s, the harmonic number, dimensionless, sampled logarithmically between 5 and 50,000,000.

theta, the angle between the ray path and the local magnetic field, measured in radians, sampled linearly between 0.001 and π/2 (namely, 1.5707963267948966).

p, the power-law index of the energetic electrons, dimensionless, sampled linearly between 1.5 and 7.

The coefficients were computed on Harvard’s Odyssey cluster using Git commit 772161 of rimphony. A total of about 5,000 CPU hours were used, with 500 processes running for about 10 hours each. There are 2,748,835 data rows in total. The data are provided in their original format, split among 500 files, so that smaller subsamples of the data may be loaded easily. A README.md file provides more detailed information.
