Off-set pointing (OSP) potential problem. Results of OSP available in 7-10 days.
Need to exchange 292 faulty British Aerospace supplied capacitors.
Solar tests performed at Davos.
Science meeting to be held in March.
CCD contamination detected. Thomas: source is likely Silicon.
Gradient in continuum image detected, caused by polarizing beam splitter. Beam splitter will be exchanged.
Instrument has successfully measured P-modes from the ground.
All requirements met with XDL detectors, except total count rate.
More power needed with XDL.
Problems with telescope and grating focus mechanism.
Ground testing being performed.
Serious violation of 3" (arcsecond) resolution criterion for Zeiss mirror: 7" measured in spatial dimension.
With this resolution 40% scatter contribution expected in coronal hole, so valid science can still be done.
Problem with leaky door. Tightness to be verified in vibration test. Refurbishment of two qualification motors.
No schedule change for XDL since M-CDR review in Nov. '93. Delivery scheduled for Sept., Oct. '94.
Problem in OVI spectrometer: low efficiency in grating.
Roll rate reduction might reduce induced jitter to acceptable level. Study needed.
Spartan-201-1 data on polar coronal hole successful.
Problems with 6 flight motors and doors.
Schedule getting very tight.
SWAN cannot meet ESA integration schedule. MMS delivery for integration
expected by end of April '94.
Overall instrument efficiency factor 3 too low. Cause still unknown.
STOF FM unit delivery delayed by more than one month, due to technological problems and illness of key personnel.
Problems: (1) outgassing of p-tolualsulfonamide. Source needs to
be identified and removed before S/C testing.
(2) EPHIN Si(Li) semiconductors need be replaced. FS not available until June '94.
ESU delivered without mechanical qualification due to failure in
vibration test. Must be returned in Feb. for qualification tests.
CEPAC TV contamination problem: see COSTEP report.
