Subject:	TWP/TSI/C1 - mirror continuously spinning
DataStreams:	twptsicldmaskC1.a1, twptsiskycoverC1.b1, twptsiskyimageC1.a1
Description:	The mirror and associated shadowband went into a mode of continuously spinning, sometimes clockwise and sometimes counterclockwise, so the sun was not blocked.
Measurements:	twptsicldmaskC1.a1: PNG data stream - documentation not supported(png) twptsiskyimageC1.a1: JPG data stream - documentation not supported(JPEG data stream - documentation not yet available) twptsiskycoverC1.b1: Percentage thin cloud(percent.thin) Pixel count: number total opaque(count.opaque) Pixel count: number total in processed circle(count.sky) Pixel count: number opaque in sun circle(region.sun.count.opaque) Pixel count: camera and sun strip mask(count.mask) Pixel count: number thin in sun circle(region.sun.count.thin) Pixel count: number total thin(count.thin) Percent opaque cloud(percent.opaque) Pixel count: number total between horizon and processed circle(count.sub.proczen) Pixel count: number total in sun circle(region.sun.count)

Subject:	TWP/TSI/C1 - shadowband not moving
DataStreams:	twptsicldmaskC1.a1, twptsiskycoverC1.b1, twptsiskyimageC1.a1
Description:	The shadowband was stuck in a position at about 215 degrees.
Measurements:	twptsicldmaskC1.a1: PNG data stream - documentation not supported(png) twptsiskyimageC1.a1: JPG data stream - documentation not supported(JPEG data stream - documentation not yet available) twptsiskycoverC1.b1: Percentage thin cloud(percent.thin) Pixel count: number total opaque(count.opaque) Pixel count: number total in processed circle(count.sky) Pixel count: number opaque in sun circle(region.sun.count.opaque) Pixel count: camera and sun strip mask(count.mask) Pixel count: number thin in sun circle(region.sun.count.thin) Pixel count: number total thin(count.thin) Percent opaque cloud(percent.opaque) Pixel count: number total between horizon and processed circle(count.sub.proczen) Pixel count: number total in sun circle(region.sun.count)

Subject:	TWP/TSI/C1 - hazy image
DataStreams:	twptsiC1.00, twptsicldmaskC1.a1, twptsiskycoverC1.b1, twptsiskyimageC1.a1
Description:	Moisture in the camera lens and filter caused the sky image to be very "hazy". The lens and filter were cleaned, the moisure seals were checked, and desiccant was added to both the camera housing and main electonics enclosure.
Measurements:	twptsiC1.00: Raw data stream - documentation not supported(raw) twptsicldmaskC1.a1: PNG data stream - documentation not supported(png) twptsiskyimageC1.a1: JPG data stream - documentation not supported(JPEG data stream - documentation not yet available) twptsiskycoverC1.b1: Pixel count: number thin in zenith circle(region.zenith.count.thin) Pixel count: number thin in horizon area(region.horizon.count.thin) Percentage thin cloud(percent.thin) Pixel count: number total indeterminant(count.unknown) Relative \'strength\' of direct sun(sun.strength) Pixel count: number opaque in sun circle(region.sun.count.opaque) Pixel count: number total in horizon area(region.horizon.count) Percent opaque cloud(percent.opaque) Pixel count: number below horizon in image(count.sub.horz) Pixel count: number total in processed circle(count.sky) Pixel count: number total opaque(count.opaque) Pixel count: number opaque in zenith circle(region.zenith.count.opaque) Pixel count: number total in zenith circle(region.zenith.count) Pixel count: camera and sun strip mask(count.mask) Pixel count: number thin in sun circle(region.sun.count.thin) Pixel count: number total thin(count.thin) Pixel count: number opaque in horizon area(region.horizon.count.opaque) Pixel count: number total between horizon and processed circle(count.sub.proczen) Pixel count: box, outside mirror area(count.box) Pixel count: number total in sun circle(region.sun.count)

Subject:	TWP/TSI/C1 - moisture in camera housing
DataStreams:	twptsiC1.00, twptsicldmaskC1.a1, twptsiskycoverC1.b1, twptsiskyimageC1.a1
Description:	Water infiltrated the camera housing after periods of heavy rain causing moisture to collect inside the neutral density filter, corrupting the images. The filter was cleaned, o-ring seal checked, and camera housing sealed where it joins the arm.
Measurements:	twptsiC1.00: Raw data stream - documentation not supported(raw) twptsicldmaskC1.a1: PNG data stream - documentation not supported(png) twptsiskyimageC1.a1: JPG data stream - documentation not supported(JPEG data stream - documentation not yet available) twptsiskycoverC1.b1: Pixel count: number thin in zenith circle(region.zenith.count.thin) Pixel count: number thin in horizon area(region.horizon.count.thin) Percentage thin cloud(percent.thin) Pixel count: number total indeterminant(count.unknown) Relative \'strength\' of direct sun(sun.strength) Pixel count: number opaque in sun circle(region.sun.count.opaque) Pixel count: number total in horizon area(region.horizon.count) Percent opaque cloud(percent.opaque) Pixel count: number below horizon in image(count.sub.horz) Pixel count: number total in processed circle(count.sky) Pixel count: number total opaque(count.opaque) Pixel count: number opaque in zenith circle(region.zenith.count.opaque) Pixel count: number total in zenith circle(region.zenith.count) Pixel count: camera and sun strip mask(count.mask) Pixel count: number thin in sun circle(region.sun.count.thin) Pixel count: number total thin(count.thin) Pixel count: number opaque in horizon area(region.horizon.count.opaque) Pixel count: number total between horizon and processed circle(count.sub.proczen) Pixel count: box, outside mirror area(count.box) Pixel count: number total in sun circle(region.sun.count)
