“…As time passes UKIRT and JCMT have adopted more and more shared infrastructure. 67 Starting with the release of ORAC-DR in 1998 the JAC has continued to benefit from sharing the software and each telescope has received updates that would not have been possible if we had retained separate software groups.…”

For more than a decade the Joint Astronomy Centre has been developing software tools to simplify observing and make it possible to use the telescopes in many different operational modes. In order to support remote operations the data handling systems need to be in place to allow observation preparation, flexible queue scheduling, data quality pipelines and science archives all to be connected in a data-driven environment. We discuss the history of these developments at UKIRT and JCMT and how the decision to combine software development at both telescopes led each to get features that they could not have justified if they were treated independently.

“…The JCMT-OT is the sub-millimeter ground-based telescope version of the generic JAC-OT written by the Joint Astronomy Centre that also supports the United Kingdom Infrared Telescope (UKIRT). [26][27][28] It supports the HARP heterodyne receiver 29 and the SCUBA-2 bolometer array, 30 which are similar to CHAI and SWCam.…”

CCAT will be a 25m diameter sub-millimeter telescope capable of operating in the 0.2 to 2.1mm wavelength range. It will be located at an altitude of 5600m on Cerro Chajnantor in northern Chile near the ALMA site. The anticipated first generation instruments include large format (60,000 pixel) kinetic inductance detector (KID) cameras, a large format heterodyne array and a direct detection multi-object spectrometer. The paper describes the architecture of the CCAT software and the development strategy.Comment: 17 pages, 6 figures, to appear in Software and Cyberinfrastructure for Astronomy III, Chiozzi & Radziwill (eds), Proc.

“…The OCS has been developed with simple, standardized interfaces between tasks to minimize the communication complexity between the tasks that are involved in performing an observation. The OCS also makes use of software re-use concepts, particularly in the observing queue, because the same software will run at both UKIRT and JCMT 10 . The combination of the OCS, HARP-B, and ACSIS will greatly increase the scientific output of JCMT in the coming years.…”

The James Clerk Maxwell Telescope (JCMT), the world's largest sub-mm telescope, will soon be switching operations from a VAX/VMS based control system to a new, Linux-based, Observatory Control System 1 (OCS). A critical part of the OCS is the set of tasks that are associated with the observation queue and the observing recipe sequencer: 1) the JCMT observation queue task 2) the JCMT instrument task, 3) the JCMT Observation Sequencer (JOS), and 4) the OCS console task. The JCMT observation queue task serves as a staging area for observations that have been translated from the observer's science program into a form suitable for the various OCS subsystems. The queue task operates by sending the observation at the head of the queue to the JCMT instrument task and then waits for the astronomer to accept the data before removing the observation from the queue. The JCMT instrument task is responsible for running up the set of tasks required to observe with a particular instrument at the JCMT and passing the observation on to the JOS. The JOS is responsible for executing the observing recipe, pausing/continuing the recipe when commanded, and prematurely ending or aborting the observation when commanded. The OCS console task provides the user with a GUI window with which they can control and monitor the observation queue and the observation itself. This paper shows where the observation queue and recipe sequencer fit into the JCMT OCS, presents the design decisions that resulted in the tasks being structured as they are, describes the external interfaces of the four tasks, and details the interaction between the tasks.
