Asterism Selection for MAVIS instrument
Project description
MASTSEL
This library was developed with 2 goals: support the Asterism Selection for MAVIS instrument (https://mavis-ao.org/) and managing the computation of the jitter (i.e. tip/tilt) error in Adaptive Optics simulations done in the Fourier domain. It is used by TIPTOP (https://github.com/astro-tiptop/TIPTOP).
The main features are located in:
-
mastsel/mavisLO.pyclass that computes the jitter ellipses that can be -
convolved with High Orders (HO, i.e. aberrations of higher spatial
-
frequencies than tip/tilt) Point Spread Functions (PSF) to get the PSFs that
-
consider both the effect of HO and Low Orders (LO, i.e. tip/tilt).
-
mastsel/mavisPsf.pythat contains a set of methods and classes to compute -
short and long exposure PSF from Power Spectral Densities (PSD), Strehl
-
Ratios, radial profiles, encircled energies (and other quantities) from PSF,
-
to convolve kernels with PSFs, …
