AirmassConstraint¶

class
astroplan.
AirmassConstraint
(max=None, min=1, boolean_constraint=True)[source]¶ Bases:
astroplan.AltitudeConstraint
Constrain the airmass of a target.
In the current implementation the airmass is approximated by the secant of the zenith angle.
Note
The
max
andmin
arguments appear in the order (max, min) in this initializer to support the common case for users who care about the upper limit on the airmass (max
) and not the lower limit. Parameters
Examples
To create a constraint that requires the airmass be “better than 2”, i.e. at a higher altitude than airmass=2:
AirmassConstraint(2)
