Chandra/Hubble Deep Field North (Superseded)
The data from the Chandra/Hubble Deep Field North are public as of 20 April 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 12 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 two files.]
| File | Size (MB) | Contents |
|---|---|---|
| cdfn_p_l2.tar | 134 | Primary products: Level 2 |
| cdfn_p_l1.tar | 1756 | Primary products: Level 1 |
| cdfn_s.tar | 227 | Secondary products |
| V&V directory | 0.1 | V&V reports |
We have also pre-packaged the data products in single tarfiles by ObsId.
The CDFN comprises the following observations (click on the ObsId to retrieve the data, on the SeqNum to see the image):
