When I output my collection as a .csv there are three batches of data – like this:
According to an entry on this forum:
“Once you export the data, you will get a CSV file with the raw data divided into three “batches”: Spectrum, wr_raw and sample_raw.
The first batch of scans is the reflectance spectrum (R) – how much of the light is reflected back by the sample. The second batch is the raw signal from the sample (S), and the third is the raw signal from the calibration (C).
In order to calculate reflectance we use this formula: R=S/C.”
But, 1.0076935 is not equal to 461.8208 / 168.53156….
So I thought perhaps it would work from the averages across all wavelengths for that scan:
Average spectrum: 1.00009604
Average wr_raw: 145.141416
Average sample_raw: 52.72259867
And again, R=S/C does not work…
Can you please explain?
