SAT Scanning Strategies I

March 2019

Background

In this post we collect results from separate SAT scanning studies for Chile (Deeper SAT from Chile and Deeper SAT from Chile II) and the South Pole (Deep SAT from the Pole, Wider SAT from the Pole and Wider SAT from the Pole II).

Comparison

Here is a table of the scanning strategies and the resulting depth maps:

Name	el_min [deg]	el_max [deg]	fsky (raw)	fsky (noise)	fsky (signal)	max. depth [µK/arcmin]
Chile deep	45	60	0.516	0.182	0.059	3.25
Chile deepest	35	60	0.501	0.158	0.047	3.00
Pole widest	40	60	0.138	0.073	0.047	3.01
Pole wide	45	60	0.120	0.065	0.043	2.81
Pole deep	50	55	0.050	0.029	0.019	1.78

The Chile deepest and the Pole widest maps have the same maximum depth. We show here the binned depth maps. First for Chile:

and then for the Pole:

to show the difference in sky area. Each color corresponds to a 1µK range in depth.
