Updating and Improving the MOIRCS Acquisition Software for Subaru Telescope
Project Site: Subaru Telescope
Mentor: Russell Kackley

Project Abstract:

Subaru Telescope possesses a unique instrument called the Multi-Object InfraRed Camera and Spectrograph, otherwise known as MOIRCS. MOIRCS uses telescope masks containing thin slits, which must be lined up very precisely with the targets of the spectrograph. The software that exists for this purpose, MOS Acquisition, is outdated and difficult to use. It uses PGPlot, a C library for displaying images that was last updated in 2001. The outdated nature of the software causes it to be unintuitive, as the cursor often teleports around the screen unexpectedly, and upon clicking, the user is often left with no indication as to whether the click registered or not. To rectify these issues, the MOS Acquisition software was rewritten in Python using Ginga, an astronomical image-display program written and maintained by Subaru’s software division. Because Ginga is more modern than PGPlot, it conforms to many of the standards expected from modern applications, such as buttons that visibly depress when you click on them, and a red ‘X’ in the corner that can be used to abort the program at any time. Many useful features were also added, such as undo and redo buttons, allowing actions to be revoked at any time. The final program is far more user-friendly than the original MOS Acquisition program. It will save astronomers on the summit significant amounts of time to be spent observing with, rather than aligning, the telescope.
