MoonIlluminationConstraint#
- class astroplan.MoonIlluminationConstraint(min=None, max=None, ephemeris=None)[source]#
Bases:
Constraint
Constrain the fractional illumination of the Earth’s moon.
Constraint is also satisfied if the Moon has set.
- Parameters:
- minfloat or
None
(optional) Minimum acceptable fractional illumination (inclusive).
None
indicates no limit.- maxfloat or
None
(optional) Maximum acceptable fractional illumination (inclusive).
None
indicates no limit.- ephemerisstr, optional
Ephemeris to use. If not given, use the one set with
solar_system_ephemeris
(which is set to ‘builtin’ by default).
- minfloat or
