calc_reward_function(conditions)

Parameters:

conditionsrubin_sim.scheduler.features.Conditions object

Returns:

rewardfloat (or array)

check_continue(observation, conditions)

This method enables external calls to check if a given observations that belongs to this survey is feasible or not. This is called once a sequence has started to make sure it can continue.

XXX–TODO: Need to decide if we want to develope check_continue, or instead hold the sequence in the survey, and be able to check it that way.

generate_observations_rough(conditions)

Returns:

one of:

1. None

2. A list of observations
