0120:0238   checking beam spot size, harp scans, aspect ratio



BCM = 4.8 microA (raster is OFF)

OTR is 0.200x0.153 mm.  To get a good OTR reading, I had to (1) put the OTR in, (2) turn off the viewer lights, & (3) adjust the gain.  i will do two HARP runs per setting to check consistency.

	417x225 => MCC making changes

	156x243 => MCC making changes

2440	120x234

2441	122x226

harp 2445 was run coincident with right arm run 3646

OTR is now reading 0.101x0.176 mm.
