Standard #	Signal (mV)	Reflectance (%)
#1	68.9	5.22
#2	111.2	10.44
#3	187.4	19.22
#4	504	48.3
#5	887.2	70.19
#6	1590.2	98.25

Number of standards used for calibration:	6
Overall calibration quality:	 Good
Overall residue for polynomial fit:	348.941

4 standard(s) with excellent fitting:	 #1 #2 #3 #6
2 standard(s) with poor fitting:	 #4 #5

*** Information about the fit of individual standards is only indicative: because of the way polynomial regression works, the standard(s) responsible for a bad calibration quality might appear with a perfect fit, and vice-versa.

Background (mV):	N/A

Optical parameters
Fraction of collimated photons:	0.967
Reflectance of sphere wall:	0.989

Electronics gain:	1,558
