Function for an elliptical Lorentzian profile.

Parameters:

coordstuple of arrays

row,col coordinates of image.

baselinefloat, optional

Background flux level. Defaults to 0.

dpeakflat, optional

Maximum flux value. Defaults to 1.

col_meanfloat, optional

col coordinate of star location. Defaults to 0.

row_meanfloat, optional

row coordinate of star location. Defaults to 0.

col_sigmafloat, optional

col component of Lorentzian width. Defaults to 1.

row_sigmafloat, optional

row component of Lorentzian width. Defaults to 1.

thetafloat, optional

Angle the major axis of the Lorentzian is rotated from the column axis in radians. Defaults to 0.

Returns:

g1d array of floats

Flattened 2D Lorentzian array.
