A requested value near 0.320 usually yields the desired response value of 0.300. Protects array when not in use. Using 8 low noise reads reduces read noise to 35 electrons RMS, compared with 60 electrons RMS for a single read. Read noise increases again for more than 8 low noise reads. See elsewhere in the manual for formulae relating wavelength and encoder values.
Wildfire waits a predetermined time for any given mechanism motion.
Often the mechanism is still moving even after wildfire expects the motion to be completed. Do not issue another command until the mechanism has actually stopped. Verify this by visual inspection of the motor shafts protruding from the dewar or by waiting 60 seconds. Default is off, but should be turned on to automatically archive instrument behavior. Picture number increments automatically after each exposure.
