1) Scan mirror piezo:
Set slits to

Slit	H Size (um)	V Size (um)
PBS	2	2
NES	2	2
BDA	0.025	-

and scan mirror piezo +/- 1 V. Set mirror piezo to the maximum.

2) Scan DCM roll:
Set slits to

Slit	H Size (um)	V Size (um)
PBS	0.2	2
NES	0.2	2
BDA	0.025	-

and scan roll +/- 0.25 mrad. Set roll to maximum, but correct for back lash.

3) Scan DCM pitch:
Set slits to

Slit	H Size (um)	V Size (um)
PBS	2	2
NES	2	2
BDA	0.025	-

and scan pitch +/- 0.05 mrad. Set pitch to max.

4) Scan DCM Bragg:
