m obdb=0
check with s obdb must be ~0. mm for home
to put the dichroic in as pwfs@vm-pwfsserver
prtcInsertDichroic
check with show -s ao obdb and it should show ~220. mm
Modulator:
must be between 0 and 1V
amplitudes centers
Ok: 550 0.16 0.17 0.50 0.50 0.00 90.00
channels for center: k2:ao:pmod:offsetX k2:ao:pmod:offsetY
so the position must be 0< | center + amplitude| < 1
scale is ~ 1V/arcsec

CRED2 Display (Tracking Camera)
Bring up an xterm: pwfs@vm-pwfsserver (from the k2aoserver-new VNC pull down)
2. ssh -X nfiudev@nfiuserver (the usual AO password for VNC)
3. [nfiudev@nfiuserver ~]$ cd src/sce
4 [nfiudev@nfiuserver sce]$ ./psfDispTiny.py -s /tmp/TC_Display_images.im.shm
Another option is to bring up the VNC where the FIU camera is running an eavesdrop on that:
nfiuserver:2 <usual AO password>

PyWFS Quick Access
Launch with
[pwfs@vm-pwfsserver ~]$ prtcQuickAccess.py
to center the modulator:
open the loops

Instructions for Restarting the PyWFS camera (Saffira): (from Sylvain)
Symptom: PyWFS Camera (in the PyWFS status) shows red and says it is powered off
Clicking on it and rebooting/restarting the camera server does NOT resolve this.
Solution:
Connect to the RTC: ssh -X prtc@prtcserver
showRTProcess: it opens a window and the 2nd process from the top is partially crash
Ctrl-c to restart the process
Then connect to: ssh -X pwfs@vm-pwfsserver
Issue command: prtcRestartCOM (takes about 5 sec, then you should be able to reacquire the camera)
