| - | * Reinitialize the NIRO Filter Wheel. Open the niro_filter_gtk and click REINIT. Check to see if the indicator wheel on the NIRO camera is pointing to the correct filter after it is homed. Do not turn the wheel by hand. If it points to the wrong filter, home the filter wheel, and compare counts for each filter (or look for metrology light in J-band) to confirm the correct filters are in position. Then loosen the screw on the indicator wheel and align so that it points to the correct filter label. | + | * Reinitialize the NIRO Filter Wheel. Open the niro_filter_gtk and click REINIT.

| * Home the engineering beam using BC1. A list of engineering beam positions for each beam is on a post-it note near the stage. Note that CLIMB_B1 and CLIMB_B2 are usually not homed and just left in their last good positions. If they are homed, the fringe positions for the CLIMB1 stages: CL1= 7.0565 mm and CL2 = 5.3224 mm. For the CLIMB2 stages: CL4= 2.9630 mm and CL5= 7.8500 mm. (See email from Judit on Aug 8, 2021.) | * Home the engineering beam using BC1.
