 Make sure the DIMM is running the whole time.
 
-1. Select a ~9th magnitude star (i.e., from the f9 catalog) and run do_shuffle to put it on the  BIB using IFU=555. Choose a star which transits 20 minutes from when you start the test.   For good seeing use 9.5-9.9 and for bad seeing select 9.0-9.5.

-2. Get on this trajectory with "go_next". The TO will need to center the star on the BIB (will require opening the PFIP shutter and retracting the ACQ camera mirror). Guide on the BIB and handshake to a guider. Start storing images on both guiders. Activate a wavefront sensor and allow to stabilize.

-3. Once you are fully set up on the target, run this command to allow !VimbaViewer to take control of the BIB:

-7. Set the exposure time to 10,000 - 20,000 micro-seconds, as needed.

-8. Start displaying images by either clicking on the [[Image(VimbaViewer_Freerun.png)]] button, or typing Ctrl-F, or selecting the menu item `Camera->Freerun`. Make sure the star is not saturating (you can adjust the image scaling ("Gain"), and it should not be blown out at the center). As long as this looks good, continue with these steps. If star is too bright (saturating) or too faint (not visible at all), you may need to reconsider your choice of star or the weather conditions.  Look at the histogram to see if you are saturated.  
+7. Set the exposure time to about 20,000 micro-seconds (that's what Hanshin needs for this test).

+8. Start displaying images by either clicking on the [[Image(VimbaViewer_Freerun.png)]] button, or typing Ctrl-F, or selecting the menu item `Camera->Freerun`. Make sure the star has at least 30 counts at its center (peak/max counts) and that the star is not saturating (you can adjust the image scaling ("Gain"), and it should not be blown out at the center). As long as this looks good, continue with these steps. If star is too bright (saturating) or too faint (below 30 counts at its peak), you will need to reconsider your choice of star or the weather conditions.
