Requesting Rosat Data From the Public Archive

To request ROSAT data from the public archive users should send an e-mail message to

NDADSA::ARCHIVES

or

archives@ndadsa.gsfc.nasa.gov

(N.B.: These addresses were current as of October 1995.)

The subject line should read

request rosat <data_type>

where <data_type>=FITS, BASIC, DERIVED, ANCILLARY, CALIBRATION or ALL.

You may also get the data via the WWW page of NDADS:

http://ndadsa.gsfc.nasa.gov/ndaads/archives.homepage.html

If you need to search their database, try:

The body of the letter should contain the dataset_id(s) in the form

w<i><ror>

where	<i>= p for unfiltered PSPC, f for filtered PSPC, or h for HRI and
	<ror> = the six digit ROR number.

You may request more than one dataset at a time

For example, to request FITS-type data from the datasets 200423 (filtered) and 200194 (unfiltered) a DECNet user would send the following e-mail:

To:	ndadsa::archives
Subj:	request rosat fits

wf200423

wp200194
