LookAheadDdfBasisFunction¶
- class rubin_sim.scheduler.basis_functions.LookAheadDdfBasisFunction(frac_total, aggressive_fraction, time_needed=30.0, RA=0.0, ha_limits=None, survey_name='', time_jump=44.0, sun_alt_limit=-18.0)¶
Bases:
BaseBasisFunctionLook into the future to decide if it’s a good time to observe or block.
- Parameters:
- frac_totalfloat
The fraction of total observations that can be of this survey
- aggressive_fractionfloat
If the fraction of observations drops below ths value, be more aggressive in scheduling. e.g., do not wait for conditions to improve, execute as soon as possible.
- time_neededfloat (30.)
Estimate of the amount of time needed to execute DDF sequence (minutes).
- RAfloat (0.)
The RA of the DDF
- ha_limitslist of lists (None)
limits for what hour angles are acceptable (hours). e.g., to give 4 hour window around HA=0, ha_limits=[[22,24], [0,2]]
- survey_namestr (‘’)
The name of the survey
- time_jumpfloat (44.)
The amount of time to assume will jump ahead if another survey executes (minutes)
- sun_alt_limitfloat (-18.)
The limit to assume twilight starts (degrees)
Methods Summary
check_feasibility(conditions)If there is logic to decide if something is feasible (e.g., only if moon is down), it can be calculated here.
