Description

The function allows to blur an array of source PSFs due to telescope jitter (shifts along X and Y and rotation). The output is a 3-D array containing blurred 2-D PSFs for each of the input sources.

Example

% PSF is an initial array of PSF images to be blurred, Cat is an array of source X, Y coordinates on a detector tile,
% Rotation, SigmaX0, SigmaY0: S/C rotation jittering angle and linear shifts (all the values are in [arcsec])
JPSF = ultrasat.jitter(PSF, Cat, 'Exposure', 300, 'SigmaX0', 2.,'SigmaY0', 2., 'Rotation', 10);
