| Abstract: |
The Dark Energy Survey is a multi-filter survey of the southern
galactic cap with two components: a wide component which visits many
fields, each ten times over the course of five years; and a
time-domain component of ten fields revisited on a regular cadence in
each of four filters through the survey. Optimal selection of an
observation for any particular time depends on many factors, including
weather (including seeing), moon position and phase, image quality of
already collected exposures, and others. ObsTac is the component of
the observing software system that automates selection of observations
based on current conditions. It integrates with the observing software
through an observing queue, supporting interactive intervention by
observers. It has a modular structure that simplifies replacement of
different components of the system, including the implementation of
the tactics algorithms themselves and interfaces with data sources
that supply, for example, weather and progress data. In addition to
its use in observing, obsTac may also be used to run simulations to
evaluate strategic and tactical algorithms based on archival weather
data. |
