TWP/TSI/C3 - Missing data due to Mentor Activities
DataStreams:twptsiC3.00, twptsiskycoverC3.a1, twptsiskycoverC3.b1, twptsiskyimageC3.a1
Description:
Darwin TSI on-board image collection and processing
had been turned off for Instrument Mentor to make
fine tuning adjustments. Mentor then forgot to turn
the on-board image collection and processing back
on.  All data for this time period is missing and
unrecoverable.

TWP/TSI/C3 - Metadata Errors in NetCDF Header
DataStreams:twptsiskycoverC3.a1, twptsiskycoverC3.b1
Description:
The value of "sample_int" reported in the netCDF header is
incorrect.  The correct sampling interval is 30 seconds.

The maximum values for the variable "sunny" is incorrect.  
It should be 1, not 100 as documented in the netCDF header. 
Users should disregard the "qc_sunny" flag during this
period of time and apply their own qc check if desired.

The minimum value for the variable "solar.altitude" is
incorrect. It should be -90, not 10 as documented in the
netCDF header.  Users should disregard the "qc_solar.altitude"
flag during this period of time and apply their own qc check
if desired.

TWP/TSI/C3 - poor images
DataStreams:twptsicldmaskC3.a1, twptsiskycoverC3.b1, twptsiskyimageC3.a1
Description:
The resolution of TSI images were very poor and the colors were wrong.  The clear sky 
appeared a reddish-brown during the day causing the processed image to be 100% opaque. The 
problem was corrected when the instrument was power cycled.

TWP/TSI/C3 - camera failure
DataStreams:twptsiskycoverC3.b1, twptsiskyimageC3.a1
Description:
The TSI image was out of focus due to condensation on the camera lens and PC board that 
led to camera failure. The problem was corrected by replacing the camera with a spare and 
adjusting the shadowband.

TWP/TSI/C3 - controller board failure
DataStreams:twptsicldmaskC3.a1, twptsimovieC3.a1, twptsiskycoverC3.b1, twptsiskyimageC3.a1
Description:
The mirror control board failed and was replaced with a spare. Several images were 
collected in the iterim that should be ignored. These images include periods when the sun was 
not masked by the shadowband, the camera lens was covered by red tape to protect the CCD 
from direct exposure to the sun and, the instrument was inside the shop for repair and 
testing.
