+ | ===== Can't find fringes ===== | ||
+ | |||
+ | This is a list of simple things to check if you can't find fringes: | ||
* Were the clocks synced? Make sure the [SYNC CLOCKS] button on Cosmic Debris has been pushed to start the night. If the OPLE server does not display the correct CHARA time and the errors don't read (0) or (1), the clocks were not synced. As the VME runs on its own clock and does not use the NTP server, it can drift over the course of the night and cause problems with finding fringes, even if it was synced at the start of the night. Syncing the clocks multiple time during the night may help to avoid this hidden clock problem. | * Were the clocks synced?

- | * Did the Astrolib update on OPLE? If the job queue is stopped too soon after slewing on Cosmic Debris, the correct calculations for the carts will not be done by OPLE and you may be searching for fringes with the wrong star data. The proper star can be entered by typing hd .... into the OPLE server and hitting ENTER. | + | * Did the Astrolib update on OPLE? If the job queue is stopped too soon after slewing on Cosmic Debris, the correct calculations for the carts will not be done by OPLE and you may be searching for fringes with the wrong star data. Hit STAR ACQUIRED on CD to update ople. The proper star can also be entered by typing hd #### into the OPLE server and hitting ENTER. |
+ | * Are the PoP's correct? After a PoP change, the PoP's are sometimes not updated in CD or ople. | ||
+ | * Are the carts behaving or are there vibrations or jumps of 100 or more microns every 3-6 seconds? Restart the ople server if they persist. | ||
* Is the target a high proper motion star? Red dwarfs are close stars and can have high proper motions. Scan a wider range to see if it is outside of the usual calculated scan range. Binaries can also have very high offsets from the expected position due to mistakenly using astromod calculations from the companion star. | * Is the target a high proper motion star?

+ | * Do you have enough flux from each telescope or on each baseline? | ||
* Did you get the same star in each telescope? Sometimes a busy star field and poor pointing of the telescopes can lead to the wrong star being acquired and locked by tiptilt.

- | * Check that the carts are within delay line range (-1 to 44 meters) and errors are small. Were the carts homed before the first slew of the night? Did any carts go to the front switch after slewing? This can cause them to lose their position. Turn off the OL button to send it back to zero. If it does not track on the home switch when displaying a zero position (0.000000), it was lost. Is the E2 cart stuck at 27.97m? How are the metrology signals? Are they strong and staying white? Red signals mean one or more metrology signals have gone too low and homing carts is necessary.

* 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 after a few seconds to avoid crashing NIRO.

+ | This might mean that the gain for the tracking servo is wrong. Note that changing this gain can be dangerous, especially if you set it too high as that can cause the telescope to oscillated and damage the drives. Please only do this if you are very very sure that it is necessary. Symptoms of bad gain are: The scope over shoots the position while slewing. The star will be seen to move out of the window and may come back after a few seconds. This means the slewing gain is too low. The scope oscillates when tracking or after a slew. The star will be tracing an ellipse, figure eight or other looping shape. This means the tracking gain is too low. You can damp this out with the telescope or dome gui by disabling the scope, then re-enabling it. Adjust the gain upward and watch it on the next slew. In all cases if either gain is too high the scope will go into "Fog Horn" mode, which is bad. You always want to use the lowest gain that still allows the scope to work as best as possible. If the tiptilt tells you the scope is oscillating slowly, the gain may be too low. If it is oscillating quickly it may be too high. On 10-22-2016, the gain settings were: | Scope | AZ Slewing | ||
