empyrean.PhotometryModel

class PhotometryModel(*values)

Bases: str, Enum

Photometric model for the post-OD phase-function fit.

Mirrors empyrean::PhotometryModel. In AUTO the fit climbs a model ladder – H-only -> HG12 -> HG1G2 – admitting the richest model the arc’s phase-angle coverage and magnitude count support, and a PhotometryResult reports the model it actually fitted on model_used (never AUTO). An explicit value pins a specific model. HG12 / HG1G2 follow Muinonen et al. (2010); H-only holds the slope fixed.

rindex(sub[, start[, end]])	Return the highest index in S where substring sub is found, such that sub is contained within S[start:end].
rjust(width[, fillchar])	Return a right-justified string of length width.
rstrip([chars])	Return a copy of the string with trailing whitespace removed.
rpartition(sep, /)	Partition the string into three parts using the given separator.
splitlines([keepends])	Return a list of the lines in the string, breaking at line boundaries.
strip([chars])	Return a copy of the string with leading and trailing whitespace removed.
swapcase()	Convert uppercase characters to lowercase and lowercase characters to uppercase.
translate(table, /)	Replace each character in the string using the given translation table.
upper()	Return a copy of the string converted to uppercase.
startswith(prefix[, start[, end]])	Return True if S starts with the specified prefix, False otherwise.
endswith(suffix[, start[, end]])	Return True if S ends with the specified suffix, False otherwise.
removeprefix(prefix, /)	Return a str with the given prefix string removed if present.
removesuffix(suffix, /)	Return a str with the given suffix string removed if present.
isascii()	Return True if all characters in the string are ASCII, False otherwise.
islower()	Return True if the string is a lowercase string, False otherwise.
isupper()	Return True if the string is an uppercase string, False otherwise.
istitle()	Return True if the string is a title-cased string, False otherwise.
isspace()	Return True if the string is a whitespace string, False otherwise.
isdecimal()	Return True if the string is a decimal string, False otherwise.
isdigit()	Return True if the string is a digit string, False otherwise.
isnumeric()	Return True if the string is a numeric string, False otherwise.
isalpha()	Return True if the string is an alphabetic string, False otherwise.
isalnum()	Return True if the string is an alpha-numeric string, False otherwise.
isidentifier()	Return True if the string is a valid Python identifier, False otherwise.
isprintable()	Return True if all characters in the string are printable, False otherwise.
zfill(width, /)	Pad a numeric string with zeros on the left, to fill a field of the given width.
format(*args, **kwargs)	Return a formatted version of S, using substitutions from args and kwargs.
format_map(mapping)	Return a formatted version of S, using substitutions from mapping.
maketrans	Return a translation table usable for str.translate().
