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 66.9 5.22 #2 110.5 10.44 #3 184.9 19.22 #4 494.7 48.3 #5 841.5 70.19 #6 1583.7 98.25 Number of standards used for calibration: 6 Overall calibration quality: Poor Overall residue for polynomial fit: 753.719 *** A poor quality calibration will lead to unreliable results. It is highly 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.
