.SH NOTES |
| 83 |
+ |
Hyperspectral Radiance pictures (.hsr files) are |
| 84 |
+ |
converted to approximate RGB pixels. |
| 85 |
+ |
However, the colors may not be very accurate. |
| 86 |
+ |
Pass the HSR picture through |
| 87 |
+ |
.I rcomb(1) |
| 88 |
+ |
first if greater color fidelity is required. |
