Cas A Megasecond Observations
2004-05-07
All ObsIds that are part of the 1 Ms exposure on Cas A have become publicly available. However, because of the large size of the event files it may be more efficient to download the data from the anonymous ftp archive directly, rather than through ChaSeR. You will find the links in the following table. Note that the long observations have been split, to keep the event file size (uncompressed) under 2 GB. Be warned, though, analyzing the event files from these observations will require substantial resources, in time, storage, and compute power. When everything is complete, the L2 event files will amount to almost 20 GB.
