   * Check the instrument alignment. Is flux getting through to the detector? How long has it been since the last NIRO camera alignment? Classic and CLIMB programs can run for about an hour before the light will drift from the central pixel. Use the Classic or CLIMB gui to view the light on the pixels by clicking the PICTURE tab and then the PIXEL AREA button. Turn the camera off with the STOP button. Is the right dither power turned on? CLIMB 1 and Classic use different dithers. If Classic or CLIMB fringes are found in a scan, but not when in recording mode, the dither powers are likely not on. Are the camera settings correct for the seeing conditions and flux levels?   * Check the instrument alignment. Is flux getting through to the detector?

-  * There is a script that will display offsets for all scopes against Hour Angle to help find offsets when using MIRCX and MYSTIC.  You'll need to log into the mircx spooler computer with the command ssh spooler@mircx, then use the command fringe_predictor.  A window will pop up display the last five nights of offsets vs. HA.+  * There is a script that will display offsets for all scopes against Hour Angle to help find offsets when using MIRCX and MYSTIC.
