| DataStreams: | twptsimovieC3.a1, twptsicldmaskC3.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. |

- Pixel count: number total between horizon and processed circle(count.sub.proczen)
- Pixel count: number total indeterminant(count.unknown)
- Pixel count: box, outside mirror area(count.box)
- Sun altitude above horizon(solar.altitude)
