The Quad-camera, Wave-front-sensing, Six-wavelength-channel Speckle Interferometer (QWSSI) went through on-sky commissioning and initial science runs on the LDT during 2020B. Information about instrument capabilities and performance will be forthcoming shortly. QWSSI is expected to be the default speckle camera.
Instrument Quick Facts:
All visible channels (577, 658, 808, 880nm; 40nm bandwidth) are operational. Near-IR channels (1200, 1500nm; 50nm bandwidth) still under development. Wavefront sensor (all visible light excepting the speckle channels) is operational, but data reduction pipeline does not yet currently fold this data into the data reduction.
