Subject:	SGP/NIMFR/E13 - Centrovision filter leakage
DataStreams:	sgpnimfrE13.a1
Description:	Testing of the batch of centrovision filters being used in the NIMFR EF13 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
Measurements:	sgpnimfrE13.a1: Direct Normal Narrowband Irradiance, Filter 2(direct_norm_narrowband_filter2) Direct Normal Narrowband Irradiance, Filter 4(direct_norm_narrowband_filter4) Direct Normal Narrowband Irradiance, Filter 1(direct_norm_narrowband_filter1) Direct Normal Narrowband Irradiance, Filter 3(direct_norm_narrowband_filter3)
