SGP/AERI/E14 - Sampling rate changes
DataStreams:sgpaerich1E14.b1, sgpaerich2E14.b1, sgpaerisummaryE14.b1, sgpaeriengineerE14.b1
Description:
The sampling rate of the SGP.E14 AERI was changed 4 times during July and August 2005. 
Data quality is not affected but faster sampling rate means that less scans are coadded and 
the signal-to-noise ratio of the spectral data will be different.

The E14 scan rate was increased to rapid sampling mode to support efforts at the SGP. 
However, a hard drive failure occurred during rapid sampling. A second hard drive was 
installed. We tested the new drive to make sure there was no problem by running the system at 
regular sampling speed. There were no problems so the AERI sampling rate was increased to 
rapid sampling mode. However, during observation, it was noted that the computer and hard 
drive could not keep up with the rapid sampling rate and the spectral data badly lagged 
the summary files, usually by 8 spectra. This lag time could have caused hard drive 
corruption because files were still being written when the system was trying to restart at 
00:00 GMT. The solution to the problem was to increase the sampling rate. The sampling rates 
are listed below.

February 10 2005-July 5 2005 Blackbodies 46 coadds each, Sky view 90 coadds
July 6 2005 - July 22 2005 Blackbodies and Sky view 6 coadds each
July 23 2005 - July 28 2005 hard drive failure, no data
July 29 2005 - August 5 2005 Blackbodies 46 coadds each, Sky view 90 coadds
August 6 2005 - present Blackbodies and Sky view 12 coadds each

Dr. David Turner is preparing a VAP to reduce instrument noise when rapid sampling to the 
noise level of normal sampling. This VAP should correct the problem.
