Monopole and dipole estimation for multi-frequency sky maps by linear regression

Abstract

We describe a simple but efficient method for deriving a consistent set of monopole and dipole corrections for multi-frequency sky map data sets, allowing robust parametric component separation with the same data set. The computational core of this method is linear regression between pairs of frequency maps, often called “T-T plots”. Individual… (More)
