Notes.

^(a)

Forward efficiency.

^(b)

Main beam efficiency.

^(c)

Half power beam width.

^(d)

Typical (>80% of the pixels) effective integration time for one pixel in a 20′′ resolution map. For data with CHAMP⁺, contributions from different pixels are counted as an independent integration time, resulting in a significant decrease of t_eff at the edge, that is covered by a small number of pixels only.

^(e)

N159 E.

^(f)

N159 W.

^(g)

In 50′′ resolution map.

^(h)

Median of the baseline noise.
