Sphere wall surface (%): 0.981768 Snow surface (%): 0.015751 Photodiode surface (%): 0.000145 ---------------- Calibration data Set of reflectance standards Serial number: IS3-RS-14-02N Released on: 2014-11-19 Last revised on: 2014-11-19 NOTE: this set was last revised more than 5 years ago. Please consider recalibrating it in the near future for optimal results. Standard # Signal (mV) Reflectance (%) #1 68.2 5.22 #2 111.9 10.44 #3 186 19.22 #4 496 48.3 #5 843.5 70.19 #6 1574.3 98.25 Number of standards used for calibration: 6 Overall calibration quality: Fair Overall residue for polynomial fit: 674.376 *** A fair quality calibration will strongly reduce the system accuracy. It is advised that you go through calibration again, or revise your standards. 2 standard(s) with excellent fitting: #4 #6 1 standard(s) with good fitting: #5 1 standard(s) with fair fitting: #3 2 standard(s) with poor fitting: #1 #2 *** 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.
