  5. FORCAST Commissioning Procedures • EMI/EMC Test • MCCS Communications Functional Test • INF Pressure Test • Alignment and Setup in the Air • Pupil alignment check in the air • Frame rates (depend on background conditions) • Telescope functionality (focus, chop and nod) • Chop and nod settle times • Pointing Stability • System Characterization • Optimum instrument parameters per instrument filter mode (bias, well depth) • Optimum chop frequency • Telescope emissivity • Sensitivity (standard stars) FORCAST Trimester Review

  6. Observing Techniques for Extended Sources (to be Tested During Line Ops) • Standard chop and nod (inefficient) • Quick step-and-stare (less effective sky subtraction) • Scanning (requires fast reads and many scans) FORCAST Trimester Review
