get_esd_factor(date_time: datetime.datetime)

Get distance ratio from sun based on time of year, relative to day 1 :param date_time: datetime to search

Returns:

ratio of earth sun distnace based on datetime.

Return type:

float

verify(coszen)

Verify important geometry data such as coszen, cos_i, slope, aspect, and sky view prior to inversion.
