TimeToTwilightBasisFunction

class rubin_sim.scheduler.basis_functions.TimeToTwilightBasisFunction(time_needed=30.0, alt_limit=18)

Bases: BaseBasisFunction

Make sure there is enough time before twilight. Useful if you want to check before starting a long sequence of observations.

Parameters:

time_neededfloat (30.)

The time needed to run a survey (mintues).

alt_limitint (18)

The sun altitude limit to use. Must be 12 or 18
