Specification
The first column contains the wavelength in nanometers. The subsequent columns contain the spectral (ir)radiance for each of the measurements taken during the experiment. Your data can contain up to 5 measurements:
| Column | Required? | Description |
|---|---|---|
| 1 | Yes | Wavelength in nanometers. This should be restricted to the visible light range (380-780 nm) and contain only integer wavelengths (e.g. 380, 385, 390 ...). |
| 2 | Yes | First measurement spectral (ir)radiance in µW/mW/W per mm²/cm²/m² (per sr) |
| 3 | No | Second measurement spectral (ir)radiance in µW/mW/W per mm²/cm²/m² (per sr) |
| ... | ... | ... |
| N | No | Nth measurement spectral (ir)radiance in µW/mW/W per mm²/cm²/m² (per sr) |
