chandra_aca.manvr_mon_images.get_manvr_indices

chandra_aca.manvr_mon_images.get_manvr_indices(mon_imgs)

Get indices to split mon_imgs into maneuvers.

Since the table is already sorted by idx_manvr, this is a faster more-lightweight way to get maneuver boundaries than using astropy group_by("idx_manvr").

Parameters:

mon_imgsapt.Table

Table of monitor window images as returned by read_manvr_mon_images().

Returns:

np.ndarray

Array of indices into mon_imgs that mark the start of each maneuver, with the final index being the length of mon_imgs. This is conveniently used with itertools.pairwise().
