GriF Fabry-Perot set-up procedures

To be done by CFHT staff

Before installing the FP in the GriF spacer, the following procedures must be followed for the set-up of the FP :
 remove the Gumball densities
 check that the proper resistance has been connected in the CS 100
 adjust the potentiometers of the CS 100 front panel to the appropriate values
 close the loop on the CS 1000
 adjust by eye the parallelism of the FP

The FP can now be placed in the GriF spacer.

Then, the following procedures must be followed :
 adjust the default values of the FP parallelism
 focus the different KIR filters and GriF grism(s ?)

To be done then by the observer and/or the support astronomer (as an introduction to GriF)

Preliminary operations to be followed : from the GriF Neptune session,
 open an first Xterm window (called "GriF Xterm" in the following), type “grifin” and then “bash”
 open a second Xterm (called "IDL Xterm" in the following), on which you log on kou (with the observer login/passwd), copy /h/grif/idl/idl_setup on the home directory of the observer account, execute "source idl_setup", change to directory "/h/grif", and run idl
 open a third Xterm (called "Phase Xterm" in the following) and type “bash”

Then, the observer should follow the following procedures :
 first wavelength calibration
 check the parallelism of the FP

To be done then by the observer

The FP is now ready for astronomical observations. These are made of the following operations :
 wavelength calibration
 type in the GriF Xterm " grifsetup clean" and "grifsetup object" before doing the scan of the object (astronomical object, PSF, calibration star)
 flat field (white light cube)
