A package for estimating differential emission measures (DEMs) from observations of the Sun using Monte Carlo methods.
demcmc provides an interface for collecting information on emission lines together in one place (a list of
EmissionLine objects), and running a DEM inversion on them (using
EmissionLine object contains the intensity of an observed line, and the contribution function of that line.
The inversion is carried out using Markov chain Monte carlo (MCMC) methods, with the emcee package used to run the sampling.
demcmc does not make opinionated choices on how to run the the MCMC algorithm.
Users are forced to choose the number of MCMC steps and walkers, and are given the outputs needed to evaluate whether their choices are appropriate.
Before using this package it is highly recommended to read the emcee paper to understand how the sampling works, and what to choose for the MCMC parameters.
