– 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)
