Module Contents

class Sersic

Surface brightness described by an elliptical Sérsic profile.

This profile is described by the following parameters:

• ‘I_eff’: amplitude at the effective radius

• ‘theta_eff’: effective radius, a.k.a. Sersic radius, equal to the half-light radius

• ‘n’: Sersic index

• ‘q’: axis ratio (semi-major axis / semi-minor axis)

• ‘phi’: position angle

• ‘center_x’: position along the x coordinate

• ‘center_y’: position along the y coordinate

class Chameleon

Surface brightness described by an elliptical Chameleon profile, defined as the difference between two NIE profiles.

This profile is described by the following parameters:

• ‘A’: normalization of the profile

• ‘s_c’: core radius of the innver NIE

• ‘s_t’: core radius of the outer NIE

• ‘q’: axis ratio (semi-major axis / semi-minor axis)

• ‘phi’: position angle

• ‘center_x’: position along the x coordinate

• ‘center_y’: position along the y coordinate

class Shapelets

Surface brightness described by a shapelet basis set.

class LensedPS

Surface brightness of a set of point sources after being lensed.

This profile is described by the following parameters:

• ‘ra_list’: list of coordinates along the x axis

• ‘dec_list’: list of coordinates along the y axis

• ‘amps’: list of amplitudes

class Uniform

Uniform surface brightness profile.

This profile is described by the following parameters:

class PixelatedRegularGrid

Surface brightness described on a regular grid of pixels.

This profile is described by the following parameters:

• ‘pixels’: 2D array of pixel values

class IrregularGrid

Surface brightness described on an irregular grid of pixels.

This profile is described by the following parameters:

• ‘pixels’: set of 2D coordinates and associated pixel values (x, y, z)
