Input value between 3710 and 9762 Angstroms.
On the Phase 2 proposal, this same value would be entered for the CENTRAL WAVELENGTH on the exposure logsheet line. The FILTER and APERTURE would be set to LRF on the exposure logsheet.
This is only needed for the LRF filter. Other filters automatically compute the Central Wavelength for you.
Note that the LRF calculations are a bit slow, as the equations are rather large. Typical execution time ~12 sec. on lightly loaded machine.
