lib.Fitting.QreadMC module

lib.Fitting.QreadMC.get_maps(file)

Returns the full maps of a simulation. :type file: :param file: A fits file saved from a simulation. :type file: str

Returns:

• Reconstructed maps, convolved maps and the difference between both,

• all with a shape (#subbands, #pixels, 3).

lib.Fitting.QreadMC.get_maps_many_files(rep_simu, name, verbose=True)

Returns:

• A list with the names of all the files you took.

• Three arrays containing the reconstructed maps, the convolved maps

• and the difference between both.

lib.Fitting.QreadMC.get_patch(file, seenmap)

Returns the observed patch in the maps to save memory. :type file: :param file: A fits file saved from a simulation. :type file: str :type seenmap: :param seenmap: Array of booleans of shape #pixels,

True inside the patch and False outside.

Returns:

• Reconstructed patches, convolved patches and difference between both,

• all with a shape (#subbands, #pixels_seen, 3).

Returns:

• A list with the names of all the files you took.

• Three arrays containing the reconstructed patches, the convolved patches

• and the difference between both.

lib.Fitting.QreadMC.get_seenmap(file, badval=-1.6375e+30, rtol=1e-05, atol=1e-08)

Returns an array with the pixels seen or not. :type file: :param file: A fits file saved from a simulation. :type file: str :type badval: :param badval: The value of the pixel considered as UNSEEN :type badval: float :type rtol: :param rtol: Relative tolerance for badval :type rtol: float :type atol: :param atol: Absolute tolerance for badval :type atol: float

Returns:

seenmap – Array of booleans of shape #pixels, True inside the patch and False outside.

Return type:

array

lib.Fitting.QreadMC.make_zones(patch, nzones, nside, center, seenmap, angle=False, dtheta=15.0, verbose=True, doplot=True)

Mask a path to get different concentric zones.

Parameters:

• patch (array) – Patch you want to cut of shape (#subbands, #pix_seen, 3)

• nzones (int) – Number of zones you want to make.

• nside (int)

• center (array) – Coordinates of the center of the patch in degree (lon, lat)

• seenmap (array) – Array of booleans of shape #pixels, True inside the patch and False outside.

• angle (bool) – If True, you make only 2 zones, inside and outside dtheta.

• dtheta (float) – Size of the patch were the pointing was done (degree), by default it is 15°.

• verbose (bool)

• doplot (bool) – If True, makes a plot with the different zones obtained.

Returns:

• A list with the number of pixels in each zone.

• A list with the patch masked to get each zone.

lib.Fitting.QreadMC.pix2ang(ns, center, seenmap=None)

For each pixel observed, returns the angle between the pixel vector and the central pixel vector.

lib.Fitting.QreadMC.save_simu_fits(maps_recon, cov, nus, nus_edge, maps_convolved, save_dir, simu_name)
