skretrieval.retrieval.prior.VerticalTikhonov#

class skretrieval.retrieval.prior.VerticalTikhonov(order: int, prior_state: array = None, tikhonov: array = None)[source]#

Bases: VerticalPrior

A prior that is constructed as a Tikhonov constraint.

Parameters:

  • order (int) – Order of the Tikhonov constraint, only 1 and 2 are supported

  • prior_state (np.array, optional) – Prior state. If set to None a zero prior is used, by default None

  • tikhonov (np.array, optional) – Array of factors to multiply the constraint by, by default None

__init__(order: int, prior_state: array = None, tikhonov: array = None)[source]#
