Notes:
1.  Times do not reflect pointing problems.  In many cases the target was not
    in the aperture.

2.  Door states:	1 - 1 cm^2 small aperture
			2 - 50 cm^2 small aperture
			3 - Half aperture
			4 - Half aperture
			5 - Full aperture

3.  Slit positions:	1 - 30" diameter
			2 - 9"x116"
			3 - 30" Al
			4 - calibration hole
			5 - 18"x116" CaF2
			6 - 18"x116"
			7 - 18" diameter
4.  Key to comments:
	S/N estimates are subjective, but they correspond to the following
	approximate ranges:
			Low S/N ==> < 25 counts per 0.51 A pixel
			Moderate S/N ==> 25 < counts per 0.51 A pixel < 100
			Good S/N ==> > 100 counts per 0.51 A pixel
			No detection ==> no visible signal using standard
					 background subtraction.  Usually means
					 an upper limit of ~10 cts per pixel
