Pointing-related telescope calibration utilities.

Submodules#

calibpipe.telescope.pointing.starfitter module#

Star trajectory fitting module.

class calibpipe.telescope.pointing.starfitter.StarFitter(*args: t.Any, **kwargs: t.Any)[source]#

Bases: Component

Star trajectory fitting class.

exclude_invalid_stars#: Whether to exclude ‘invalid’ stars in the fit, which are those that not have been successfully reconstructed in the camera over the entire time period of the chunk. Setting this flag to ‘False’ will include all stars in the fit, regardless of their reconstruction status. Excluding stars that have any failed reconstruction within the chunk may result in more reliable fits but fewer stars contributing to the fit.

fit_function(x, beta)[source]#

Linear fit function for ODR.

Parameters:

xarray-like: Independent variable (reco_fov_offset)
betaarray-like: Fit parameters (dlat, dlon)

Returns:

array-like: Dependent variable (expected_fov_offset) calculated from the fit parameters and independent variable
