Subject:	SGP/NIMFR/C1 - NIMFR Centrovision filter leakage
DataStreams:	sgpnimfrC1.b1, sgpnimfrE13.a0, sgpnimfrE13.b1
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.

Subject:	SGP/NIMFR/C1 - Head connector failure
DataStreams:	sgpnimfrC1.b1, sgpnimfrE13.a0, sgpnimfrE13.b1, sgpnimfrlangleyE13.c1, sgpnimfrlangplotE13.c1, sgpnimfrod1barnmichE13.c1
Description:	The direct beam, head and tube temperatures went to zero beginning 20050105. The head connector was reseated 20050118 correcting the problem but the head signal cable was stressed again 20050120 through 20050121 resulting in poor data. Data between 20050118-20050120 may be ok but should be examined carefully.

DataStreams:	sgpnimfrC1.b1, sgpnimfrE13.00, sgpnimfrE13.a0, sgpnimfrE13.b1
Description:	Head temp values frequently dropped to 0, -50, or -100 degrees Celsius. Often this causes the filters to drop to values of zero (or act erratic) as well. On 9/23 the instrument was pulled from service and the mentor found significant damage to the instrument due to overheating. Instrument will be rebuilt.

Subject:	SGP/NIMFR/C1 - Tube heater not functioning
DataStreams:	sgpnimfrC1.a0, sgpnimfrC1.b1
Description:	The tube heater is not functioning properly. On 6/27/06, site operations personnel indicated the heater plug was found to be disconnected (The heater became disconnected on 6/12/06). It was reconnected and while the head temperature returned to normal, the tube temperatures are still bad. The purpose of the tube heater is to help prevent condensation from forming on the window. The mentor has not noticed any problems with the data resulting from the tube heater malfunction. However, since the instrument is technically not fully functional, this DQR is being issued. A repair attempt was made on June 7, 2007 that resulted in the tube temperatures reaching at times into the upper 50s and sometimes even the lower 60s. The high tube temps influenced the head temperature causing it to move into the upper 40s and sometimes the lower 50s. The heater was repaired on Oct 11, 2007. Though repaired, the instrument was configured to keep the tube temp in the lower 20s (deg C). This is acceptable, though to keep with instrument specifications the setting was adjusted to keep the temps in the upper 30s (deg C). This occurred on 8 Jan, 2008.

Subject:	SGP/NIMFR/C1 - Noise in 500nm channel
DataStreams:	sgpnimfrC1.a0, sgpnimfrC1.b1, sgpnimfrlangleyC1.c1, sgpnimfrlangplotC1.c1
Description:	The 500nm channel data were noisy at times, and at other times output "steps down" a notch. On 10/14, maintenance was performed to re-seat connection. On 10/31, the noise returned briefly, so the end-date has been extended through that date.

Subject:	SGP/NIMFR/C1 - Tube heater
DataStreams:	sgpnimfrC1.a0, sgpnimfrC1.b1, sgpnimfrlangleyC1.c1, sgpnimfrlangplotC1.c1
Description:	The function of the tube heater is to prevent dew from forming on the front window. During this period the tube heater was not functioning, there were no reports of dew, and there were no indications in the data that dew on the window was affecting data.
