Subject: | SGP/TSI/C1 - Ice storm |
DataStreams: | sgptsiskycoverC1.b1 |
Description: | The TSI images were affected by an ice storm that caused the mirror to be covered with ice, the shadowband to stop rotating, and condensation to blur the images. |

Subject: | SGP/TSI/S01 - position coordinates |
DataStreams: | sgptsiskycoverS01.b1 |
Description: | The TSI at S01 was originally configured to use the same latitude and longitude (36.607, -97.488) as the TSI at C1 but the actual coordinates of S01 are 36.601 deg, -97.481 deg. Since the ingest uses the actual coordinates, the TSI was configured to use the same. The difference is so minor, 580m, that the change did not affect the position of the shadowband. |

Subject: | SGP/TSI/S01 - Reprocess: Corrupt properties file |
DataStreams: | sgptsiskycoverS01.b1 |
Description: | The YYYMMDDHHMMSS_tsi.properties files were corrupted causing the ingest to assign incorrect values to attributes opaque_thresh, thin_thresh, cam_mir_dist, and center_x. A default properties file from 10/11/2013 was being concatenated to the current properties file before it was moved to the ingest directory, so that the last values read were from the earlier date. |

DataStreams: | sgptsiskycoverC1.b1 |
Description: | The YYYMMDDHHMMSS_tsi.properties files were corrupted when the computer operating system was upgraded, causing the ingest to assign incorrect values to attributes opaque_thresh, thin_thresh, cam_mir_dist, and center_x. A default properties file from 5/25/2004 was briefly used and then a properties file from 10/11/2013 was being concatenated to the current properties file before it was moved to the ingest directory, so that the last values read were from the earlier date. |
