First wavelength calibration

12 novembre 2008

 From the AOB GUI, go to the "Set up configuration" of the AOB

 From the DetI GUI, type "etime 1"

 Choose Kprime filter

 From the DetI GUI, type "snap" to check that one can see the artificial star


 From the AOB GUI, go to the "Observer configuration" of the AOB

 Choose Brackett gamma filter

 From the AOB GUI, put three neutral density filters for the APDs of the AOB

 On the GriF Xterm, type "grifsetup clean" to light off all Gumball lamps

 On the GriF Xterm, type "grifsetup cont" to light on the continuum lamps of the Gumball

 On the GriF Xterm, type "griffp –z -700" and "griffp –z 300" to check that the FP is scanning (fringes must move, if not reset the iotechs with the griffp command)


 Choose Kprime filter

 From the DetI GUI, type "etime 15" (if there are 2 argon lamps in the Gumball) or "etime 10" (if there are 3)

 On the GriF Xterm, type "grifsetup clean" to light off all Gumball lamps

 On the GriF Xterm, type "grifsetup argon" to light on the argon lamps of the Gumball

 On the GriF Xterm, type "grifscanfp –bcv –890 –755 –nstep 10" to make a 13-step scan of the He I line at 2.06163 microns

 When the scan is finished, on the IDL Xterm, in IDL, execute the command "calc_const_fp" to get the observed BCV profile. The program computes "BCV_cal", the BCV corresponding to 2.06163 microns

 On the GriF Xterm, type "setcalib 2.06163 BCV_cal", where BCV_cal is the value given by the IDL program (choose the one with the lowest chi2 value)
