Startup Transient |
Thermal transients in the MDI filter oven during the first 3 or 4 hours
after each "structure program" restart cause a shift in velocity and
intensity observables. These intervals have been manually marked to avoid
use of this data.

| 19 |
Uncorrected Flat Field |
On-board flat-fielding performed with non-standard table and data not
corrected for known errors.
|
TBD ? |
| 20 |
No Flat Field |
No on-board flat-fielding performed; binned and integrated data may be
flat-fielded later.
|
TBD ? |
| 21 |
Corrupt Flat Field |
On-board flat-fielding performed with corrupted table; correction requires
after-the-fact determination of on-board flat-field values at the time.
|
TBD ? |
| 22 |
I0 Filtergram Error |
On-board processing error resulting in corruption of computed continuum
values only. Generally only part of an image affected.

Manual inspection rejection of data. Reasons may include reasons that
either are or could be indicated by other trouble bits.
