DeepDrillingSurvey

class rubin_sim.scheduler.surveys.DeepDrillingSurvey(basis_functions, RA, dec, sequence='rgizy', nvis=[20, 10, 20, 26, 20], exptime=30.0, u_exptime=30.0, nexp=2, ignore_obs=None, survey_name='DD', reward_value=None, readtime=2.0, filter_change_time=120.0, nside=None, flush_pad=30.0, seed=42, detailers=None)

Bases: BaseSurvey

A survey class for running deep drilling fields.

Parameters:

basis_functionslist of rubin_sim.scheduler.basis_function objects

These should be feasibility basis functions.

RAfloat

The RA of the field (degrees)

decfloat

The dec of the field to observe (degrees)

sequencelist of observation objects or str (rgizy)

The sequence of observations to take. Can be a string of list of obs objects.

nvislist of ints

The number of visits in each filter. Should be same length as sequence.

survey_namestr (DD)

The name to give this survey so it can be tracked

reward_valuefloat (101.)

The reward value to report if it is able to start (unitless).

readtimefloat (2.)

Readout time for computing approximate time of observing the sequence. (seconds)

flush_padfloat (30.)

How long to hold observations in the queue after they were expected to be completed (minutes).

Methods Summary

calc_reward_function(conditions)	Parameters:
check_continue(observation, conditions)	This method enables external calls to check if a given observations that belongs to this survey is feasible or not.
generate_observations_rough(conditions)	Returns:

Methods Documentation

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
