Rcalc run to convolve light source SPD with standard curves. |
| 4 |
Used by scripts illumcal, reflcal. |
| 5 |
|
| 6 |
Input is wavelength (in nanometers) and output (in watts/nm/something). |
| 7 |
Variable "intvl" must be set to value spacing (in nm). |
| 8 |
Output is per-wavelength convolution as described below. |
