Chandra Deep Field South (Superseded)

The data from the Chandra Deep Field South are public as of 13 March 2001. Click for PostScript image.

For convenient download, we have pre-packaged the data products in the following three tar files and a Verification & Validation directory.

Note: The 11 ObsIds have been merged into single event and image files, after careful alignment and reprojection to a common coordinate system. Hence, these products differ from what one would get by downloading the individual ObsIds' products.

Note that these files are free from any alignment errors and that the absolute coordinates are believed to be correct.

[In order not to exceed a 2GB file size, the Level 1 event files are packaged into three files: two for the "Faint" observations and one for the "Very Faint" observations.]

File Size (MB) Contents
cdfs_p_l2.tar 127 Primary products: Level 2
cdfs_p_l1.tar 1796 Primary products: Level 1
cdfs_s.tar 270 Secondary products
V&V directory 0.1 V&V reports

The CDFS comprises the following observations (click on the ObsId to go to the retrieval interface, on the SeqNum to see the image):
