contents This introductory guide aims to provide insight to new researchers in the field of cosmic microwave background (CMB) map analysis on best practices for several common procedures. We will discuss common map-modifying procedures such as masking, downgrading resolution, the effect of the beam and the pixel window function, and adding white noise. We will explore how these modifications affect the final power spectrum measured from a map. This guide aims to describe the best way to perform each of these procedures, when the different steps and measures should be carried out, and the effects of incorrectly performing or applying any of them.
