The FUSE archive is hosted by MAST (Multi-mission Archive at Space
Telescope).
To retrieve your proprietary FUSE data, you must have an STSCI/MAST
archive retrieval account and have it authorized for the appropriate
programs.
If you do not already have a STSCI/MAST account you must first
register
for one. A new
registerant should note in the comment block of this form that he/she is
a FUSE user for program number(s) XXX1, XXX2, etc.
MAST will then set up an account for access of these proprietary
datasets, and will contact the user with an account name and password
after verification.
Users can search for and retrieve data using
the web interface.
You are highly encouraged to first read the
How to Retrieve FUSE Data from MAST
and MAST search primer
pages, before trying to retrieve data.
Helpful hints on retrieving data from the archive are given below:
- Go to the FUSE archive web page.
- Follow the link "Science Data Search"
- You can search for a dataset in many different ways -- by program ID,
target name, coordinates, etc. If you choose to search by target name,
be wary of the "name resolver". For instance, if you enter the star
name SK-67D169, and ask Simbad to resolve the name, it will fail to find
anything. It turns out that Simbad will only work on this particular name
if you enter SK-67169. If you know the exact name of the target as
it was entered on the Phase 2 form (and the way it appears in the FITS
header), then enter the target name, and do not use the name resolver at all.
It is probably easier to search on progam ID or target coordinates.
If you decide to search for the dataset using the program ID, then you can
search using "Program" or "Observation Name". If, for instance, you want
to see all observations from program A001, then just enter A001 in the
form under "Program", and hit the search key. If you want to find a
specific observation in A001, say A0010101, then in the "Observation Name"
field enter A0010101000 (NB. note the 3 trailing 0's appended to the string).
Entering A0010101* also works.
- When you get to the next page, showing the results of the search,
just mark the dataset you want to download. As of January 21, 2000,
the links to the "Data Set
Names" do not work.
The exposure times reported in the the table are not correct for
certain datasets that were archived with incorrect exposure times
in the co-added (merged) spectra [the true observation time -- sum
of all exposures -- should be the value reported divided by 8].
- When you finally get to the last step in the process, you must
choose the "NET" retrieval option if the data you are retrieving is still
proprietary. This is MAST policy. The NET retrieval requires
you to provide a password to your computer so that an FTP session can
be initiated by MAST. The password is encrypted for transfer across
the internet. When entering the path where
you want the data delivered on your computer, you can enter
any path name that is accessible from the login directory of
your FTP account.
- Although the MAST manual says that
for large retrievals, a tape can be made and mailed to the user, this is
not a general option for FUSE data (because of the cost involved).
Questions about the process of retrieving data should be
directed to the MAST Archive help desk at
archive@stsci.edu or 410-338-4547.
