- Repro V Begins
The fifth major reprocessing of the archive (Repro V) has started! Details can be found here.
- Past Notices
The 2000-2002 data from the Chandra Deep Field North have been custom processed to register all 17 individual observations astrometrically. For more information, see the README file.
There are two distinct subsets of observations, clustered around roll angles of 40 (7 ObsIds) and 140 (10 ObsIds) degrees, respectively. We excluded 3 ObsIds from 1999 which were made at a focal plane temparature of -110 degrees, since their calibration is still problematic.
We offer these types of products for download:
- Merged tar file containing the merged event file, exposure map, and image
- By-ObsId tar file containing the event list and aspect solution for each of the individual ObsIds
- Full resolution linear three-color image of merged datasets
- Full resolution enhanced three-color image of merged datasets
- Smoothed enhanced three-color image of merged datasets
