Scan Maps at 160 microns

Simple and quick simulations are made of scan maps at 160 microns. On a simulated sky (by Dole, Lagache, Puget) of 32'x32', a scan map (with 302" between each leg, i.e. almost no overlap) is created.
Fig 1:
The right panel shows a relative SNR on the map. The pattern comes from: 1) the 5 dead pixels and 2) the stim repeatability gradient generating a difference in calibration and noise. Left panel: tentative sky map multipiled by this SNR ratio
Fig 2: A second pass, shifted by 10 pixels to the right and 1 pixels to the top is simulated and coadded. Again on the right: relative SNR. left: tentative sky map multipiled by this SNR ratio
