XRT Anomaly state: 2014 June 4th — 2014 June 10th
UKSSDC response
XRT was in an anomaly state from 00:23 UT on 2014
June 4 until 17:58 UT on 2014 June 10; details are on the anomaly page.
Since the anomaly affected the quality of PC mode data, several UKSSDC facilities have been modified
in the way that they handle data taken during this period. These changes
are:
- Data downloads
- If you try to download data taking during the anomaly, a warning will
appear. You can still download the data, but please be aware of the potential
issues with PC mode data.
- Building XRT data products
- The Build XRT products web pages will not include
PC-mode data taken during the anomaly in the analysis. This website is designed to give publication-quality
datasets, and therefore it is not appropriate to include the data taken with uncertain calibration.
WT-mode data are analysed as normal.
- Auto-analysis of GRB data
- The automated analysis of ground-processed data for GRBs during the anomaly continued as normal,
with the data being posted online as soon as they were available. However, the XRT GCN circulars
were sent out manually rather than automatically, to allow the XRT scientists to check the data
for any issues related to the anomaly. Data taken during the anomaly are clearly marked
on the results web pages.
