Number 12 June 2000


1) Propose, even if you missed the NOI deadline!
2) Please use the cycle 2 template- and style-files for cycle 2 proposals
3) New Wavelength solution available (improvement on calfuse v. 1.6.9)
4) Calibration Software Upgrade and Public Distribution
5) SDAF files will no longer be distributed with the data announcements

1) Propose, even if you missed the NOI deadline!

        We'd like to remind everyone that the FUSE cycle 2 proposal deadline is 
on July 14.  As usual, a Notice of Intent was a requested, but non-compulsory 
part of the proposal process.  Hence, please feel free to propose even if no 
NOI was submitted.

2) Please use the cycle 2 template- and style-files for cycle 2 proposals

        As you start writing your cycle 2 FUSE proposal, please check that you
are indeed using the cycle 2 proposal templates and LaTeX style file, 
as these have changed slightly from cycle 1.  The best way to get these is to 
send an e-mail to 
with the word(s) help or 
request templates in the "subject" line.
        NOTE: Prior to June 5, 2000, there was a problem with Web-based 
downloads from the GSFC support site, which was providing "Cycle 1" versions 
of the template and style file!  Those requesting via e-mail, however, got 
the correct Cycle 2 versions.  If you obtained your support materials prior 
to June 5, please double check that your materials state "Cycle 2".

3) New Wavelength solution available

        A new and improved wavelength solution is now available for data
processed with the calfuse pipeline version v.1.6.9, or earlier.  As the 
dispersion solution is the last stage of the calibration pipeline there is 
no need to reprocess the data.  You may simply use the new wavelength files 
in place of the ones in the extracted spectral file.  Further details
including instructions for retrieving the new wavelength files can be found at:

4) Calibration Software Upgrade and Public Distribution

The Calfuse software was recently upgraded to version 1.7, containing
a number of improvements:
 -- new flux calibration
 -- new wavelength calibration
 -- improved geometric distortion correction
 -- more accurate spectral extraction windows
 -- extraction windows for extended sources
 -- a deadtime correction (which had been previously removed from calfuse)
 -- correction of wavelength calibration zero-point for FPA position

We are working towards a distributable version of the calfuse pipeline
software.  Currently the software runs on Sun solaris workstations.  
Public distribution is currently scheduled for later this year.

5) SDAF files will no longer be distributed with the data announcements

        As the operation of the spacecraft is getting more routine and the 
number of observations with some form or other of problem have been dropping 
dramatically, we have automated our quality control procedures.  
While the output of these automatic procedures are helpful to the project, 
the software can at times be confused by faint targets and/or emission line 
spectra.  Hence, in order to not risk confusing the observer, we will 
discontinue the distribution of the SDAF (Science Data Assessment Form) files 
with the notification that the data has been staged to MAST.  We will still 
be performing the general quality control (and the SDAF will be made available 
upon request), but as always the program PI is invited to (and ultimately 
responsible for) bringing data problems to our attention.
