Millimeter-wave map filtering and Sunyaev-Zel'dovich galaxy cluster/source detection package. Originally developed for the Atacama Cosmology Telescope project.
By default, 1/f noise becomes pathologically high as you approach ell=0. This creates unrealistic maps. In practice, the real atmosphere and the map-maker transfer function lead to zeroing of the noise on large scales. I arbitrarily set the noise for lmin<100 (default) to be zero to avoid this, and provide lmin as a parameter to simMap.
