ALFOSC focus: ~alfosc/src/tcl-uif/alfosc-interface Calibration lamps: ~alfosc/src/tcl-uif/alfosc-interface Slit x-position: ~obs/alfosc/slitpos.def Slit y-position: ~obs/alfosc/slitpos.def The slitpos files should be edited by user obs.
To edit this file, you should use the alfosc.edit-slitpos program which will test the contents of the file and tell you if everything was correct.

For horizontal slits we usually use X=1050 .
For vertical slits we usually use Y=1050 .

Note that the entries for wheel positions 0 to 7 are for slit acquisition, while further entries are to save handy CCD positions for other type of offsets.
