New Data Distribution Procedures

2004-12-02

As of 1 December 2004, CXC Operations are running DS Release 7.4. This release includes a large number of changes in the way data are being handled, with two changes that will be very visible to the users.

  1. The software that creates the V&V reports has been completely replaced. Consequently, they will look different and they will be in PDF format. The primary package will contain a V&V report that is similar in length to what you are used to. The secondary package will, in addition, contain a V&V reference document (also PDF) that is considerably longer and contains much more detail
  2. The on-line data distribution will no longer work through pre-packaged tar files that are put in an ftp staging area. Users (PIs and Observers) will still be notified that new data have become available, but they will be directed to retrieve the data through WebChaSeR using its login feature (either the proposal or PI account) as long as the data are proprietary; the e-mail message will contain a reminder of relevant information. Please note that anybody can retrieve the non-proprietary data products for a proprietary observation. But one needs to be logged in to the authorized PI or proposal account in order to have the proprietary products (in particular, the event files and the images) included in the retrieval package.
