Subject:
SGP/MFRSR/C1 - Out-of-band filter leakage
DataStreams:sgpmfrsrlangplotC1.c1, sgpmfrsrC1.a0, sgpmfrsrC1.b1, sgpmfrsrlangleyC1.c1
Description:
Testing of the batch of centrovision filters being used in the MFRSR C1 instrument 
indicate that the first four filters leak 'out of band' light. The leakage for each filter is 
(1)415nm 3%, (2)500nm 1-2%, (3)615nm 1-2%, (4)673nm 3%. Acceptable leakage is less than 0.5%.

This leakage causes an error in the irradiance values (too high) at these four wavelengths 
and the optical depths calculated using this data will be too high.
Suggestions: 
Use sgpmfrsrE13 data; instruments are in close proximity.
