Summary, Feedback and General discussion: Steven Federman, FOAC Chair
- What a difference a year makes!!
- Most 'anomalies' now characterized and can be treated in data pipeline
- The FUSE Team deserves a round of thanks to bring us to this stage
- Also learned of experiences of GI's and how their trials/tribulations
were resolved (usually in close touch with the FUSE team)
- Mission Status
- Things are running smoothly
- New capabilities include offset acquisitions, moving targets,
'FP-SPLITS', and new version of pipeline (V1.9 due out in March)
- V1.9 incorporates 1-dimensional flat field, new wavelength solution,
and sophisticated background correction
- Things to Note
- Look at trailer files for key information
- Detector pixels not real pixels - size affected by temperature, etc.
(treated in pipeline)
- Pulse height corrections, especially for faint sources
- Wavelength calibration good to +/- 4 pixels (except for portions of
segment 2b which are 2 to 3 times larger)
- Wavelength offset between segments about 0.2 A
- Event Bursts have returned, but are treated in new pipeline
- LiF1b not for absolute fluxes
- Line spread function (LSF) more complicated than anticipated with
at least 2 Gaussians of 7 and 18 pixels (affects narrow lines)
- Day time spectra of SiC channels show solar emission features
- There are difficulties with extended sources
- Cycles 1 and 2
- MDRS and HIRS observations done according to visibility of targets
- PI can be notified about 1 week before observation
- Positive Senior Review led to extended 2-year mission (at reduced
funding)
- Cycle 3
- About 1500 ksec available for large projects
- S/N ratios greater than 30 are sometimes possible
- Night observations must be budgeted correctly (request 160% of night
total)
- CVZ observing possible, if justifiable
