Infrared Relectance Standards Survey

Infrared Reflectance Standards Survey
INSTRUCTIONS:

"PRIORITY" pick a priority level from the drop down menu:
1 = high
(a critical parameter; SRM of no value without it)
2 = medium
(important for calibration purposes, but not absolutely essential)
3 = low
(useful, but icing on the cake)
0 = zero
(not important, immaterial)
4 = none
(don't know or no opinion)
