rubin_sim.maf.maps.galplane_priority_map(nside=64, get_keys=False, ra=None, dec=None, pixels=None, interp=False, map_path=None, use_alt_maps=False)

Reads and saves the galactic plane priority maps.

nside: `int`

Healpixel resolution (2^x). At present, this must be 64.

get_keysbool, opt

Set this to True to retrieve only the keys (such as the science map names) for the maps. Default False.

ranp.ndarray or float, opt

RA (can take numpy array). Default None sets up healpix array of nside. Radians.

decnp.ndarray or float, opt

Dec (can take numpy array). Default None set up healpix array of nside. Radians.

pixelsnp.ndarray, opt

Healpixel IDs, to sub-select particular healpix points. Default uses all points. Easiest way to access healpix values. Note that the pixels in the healpix array MUST come from a healpix grid with the same nside as the galactic plane priority map. Using different nsides can potentially fail silently.

interpbool, opt

Should returned values be interpolated (True) or just nearest neighbor (False). Default False.

map_pathstr, opt

Path to directory containing dust map files. Default None, uses $RUBIN_SIM_DATA_DIR/maps.

use_alt_mapsbool, opt

Use the priority_GalPlane_footprint_alt_map_data_{ugrizysum}.fits files instead of the default priority_galPlane_footprint_map_data_{ugrizysum}.fits files. Default False.
