If there are archival images that you would like to work with (see Chapter 2.1 to find out how to look up images in the Merged Observing Log), you may retrieve them from the NSSDC Data Archive and Distribution Service (NDADS) with IUEFX. The calling sequence for IUEFX is
where ``DTYPE'' is the data type wanted (see Table 2.2 for examples).
The ``mode'' keyword allows you to specify where the files will be copied to. It may be set equal to a number representing the output destination directory of the data files:
0 User's current working directory (you will be asked to specify your password). This is the default mode.
1 Account to be specified by user (the program will need the password for the account given).
2 Generic account on IUE (you can access the files as IUE::IMAGET).
3 NDADS staging area (directory syntax is ndadsa::anon_dir:[data_dist.iue]).
If you request to have files copied to an account on a node other than the one you are logged onto, you may specify another node with the ``node'' keyword.
You may also, for IUESIPS data, specify a file format with the ``ftype'' keyword. The available formats are RDAF (the default), GO, and GO-Split (GO format with the VICAR label in a separate file).
If you have a list of camera and image sequence numbers already written in a file, you may submit that list to NDADS with IUEFX using the ``file'' keyword.
Example: If you want to call over the ELBL and MELO files in GO format for LWP 9021 and LWP 9022 into your own account on CHAMP from NDADS, you would type
You would then answer the questions and type in the camera and image sequence numbers of the images you wanted in this format:
lwp9021 and return
lwp9022 and return
hit return again to end
The NDADS system will send you a mail message to let you know whether it found your images or not.
If NDADS is operational, your images may be returned in a few minutes. Lately however hardware problems have resulted in delays of several hours or more. To check on the status of your NDADS job, you may send an e-mail message to firstname.lastname@example.org or NDADS::ARCHIVES. Type STATUS on the subject line and leave the body of the message blank. You should get a reply that should tell you the status of all the jukeboxes (they will be ``online'' if available or ``offline'' if unavailable). You may see a message about your job in there if your job is currently being executed. Alternatively, you can check the WEB page at:
If the images you requested do not appear in your account and NDADS sends you a mail message that says that it ``failed to copy'' your files, but that they may already exist in the staging area, you can look for them in the staging area and copy them yourself (note the leading zero in the image sequence number):
copy ndadsa::anon_dir:[data_dist.iue]lwp09021slg.* *.*
copy ndadsa::anon_dir:[data_dist.iue]lwp09021LLG.* *.*
INTERNET users can get files from the staging area via anonymous FTP. Files must be transferred in binary mode. The TCP/IP address for NDADSA is 184.108.40.206.
Note that IUE data is no longer subject to any proprietary period. All data is available to the public as soon as it is archived. This applies to both IUESIPS and NEWSIPS data sets.
