Mapping

We can map a TOD (or several of them) with a Mapper. The simplest possible mapper just bins the data:

from maria.mappers import BinMapper

mapper = BinMapper(center=(150, 10),
                   frame="ra_dec",
                   width=1e0,
                   height=1e0,
                   resolution=5e-3,
                   tod_preprocessing={
                        "window": {"name": "tukey", "kwargs": {"alpha": 0.1}},
                        "despline": {"knot_spacing": 5},
                        },
                   map_postprocessing={
                        "gaussian_filter": {"sigma": 1},
                        "median_filter": {"size": 1},
                        },
                   units="K_RJ",
                   tods=[tod],
                   )

output_map = mapper.run()

where we define the preprocessing to be done on the TOD. We can see the output with

output_map.plot()
