top source eve_get_wave_bin

result = eve_get_wave_bin(wavelength [, megsa=megsa] [, megsb=megsb] [, l2=l2] [, inverse=inverse])

Given a wavelength, find the index of the wave array which is closest to it.

You should set exactly one of /megsa, /megsb, and /l2. If none are set, the function returns zero. If more than one is set, the first one in the priority list /megsa, /megsb, /l2 is chosen

Return value

If /inverse is not set, index in the appropriate wave array matching this wavelength. If /inverse is set, wavelength matching this index.

Parameters

wavelength in required

input wavelength in nanometers

Keywords

megsa in optional

if set, use MEGS A wavelength scale

megsb in optional

if set, use MEGS B wavelength scale

l2 in optional

if set, use Level 2 wavelength scale

inverse in optional

if set, treat wavelength as an index instead of a wavelength and find the wavelength that matches the index
