Technical (2006-Present): 1. Scheduling: This includes laying out the individual programs sent by the Director that had passed the science committee, ensuring the time that was requested was given appropriately and in the correct amounts and did not conflict with time specifically denoted unavailable. Care must be taken to ensure that simultaneously scheduled programs were on selected beams that do not overlap. Interpersonal skills are necessary to resolve problems with scheduling between the instrument PI’s and the more than 30 project PI’s involved if compromise is needed for telescope assignments or time conflicts and managing observations when multiple programs were assigned on the same night. 2. Optical Setup: On any given night, the “at use” instruments and optical beam train must be aligned on the optical axis of the lab fiducial laser. This includes telescope configuration, fixed baseline length changes, and alignment of the 21 mirror beam train/optical lab. There are currently five separate instruments in the CHARA optical laboratory each of which has its own alignment procedure and baseline requirements which need to be followed for observation to commence. 3. Observational support: The Array runs 1-3 beam combiners simultaneously on different telescopes on different targets and any of those are able to be operated remotely from facilities in France, Sydney, Atlanta, and Michigan. Operators are also responsible for opening, securing, and closing the individual telescopes at startup/shutdown and have final decision on inclement weather conditions that may affect the telescopes, mirror coatings or facilities. 4. Troubleshooting/Supervising: All software in use by the Array was written and developed in-house using RT/Linux and has many known issues that can arise during an observing session. If something is not working properly and is impeding observations, operators trained to fix all but the most serious alignment, technical or software problems.
