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)
