D2 calibration lamp test
•
Activity – Internal flatfields in major UV filters; Baggett
•
Objectives – verify health and performance of D2 lamp, assess status of
major UV filters, establish baseline of internal D2 flats
•
Status – each flatfield compared to similar ground flat.
•
Results
» Overall lamp output on-orbit is 1-6% higher than in TV3.
» Out of 2 of 11 lamp turn-ons had delayed firings of a few sec
(Richardson & Swain).
» Low-frequency structures are evident in the same locations and to
the same level (up to 2-3% peak to peak) as in TV3.

- Ratio of on-orbit internal
calsystem flatfields to similar
TV3 ground data
- Stretch is +/-7%; next slide
shows sample cuts
- Large scale ‘ripple’ features
and ‘cookie’ spot at bottom of
amp C are similar to those seen
on ground (see last two slides);
filter-independent. F300x
relatively featureless except
f373n
for painted pinholes.
- Vignetting apparent in some
filters but not all.

average of 100 columns in the
right part of D quadrant
- Scale is the same on all plots
(0.96 – 1.1)
- No obvious reason for flat

and it was taken at the end of
visit which included f200lp,
f280n, f218w, f225w, & f275w.

Due to droplet cores saturating, on-orbit program acquires three nominal exposure time D2 flats in each UV filter and one short exposure time.
Ratios for short and long have been kept separate (noted in expt column).
