The main goal of Commander is to perform joint Bayesian component separation and model estimation of the CMB data (see http://arxiv.org/abs/0709.1058). Here we describe everything that can go into a Commander analysis of CMB data; of course, one is free to sample only a subset of the parameters in a given run.
The input is a number of maps, indexed by \(i\), each containing the following information:
Bandpass shift:
Gain \(g_i\):
Synchrotron, \(A^s_p (\frac{\nu}{\nu_\text{ref}}^{\beta + C \log(\frac{\nu}{\nu_\text{ref})}\):
Currently only power spectrum estimation is supported:
