QUALITY INDICATORS
Quality Indicator Bit Field
If a bit is on (=1) then the statement is true.
bit 31: do not use scan for product generation
bit 30: time sequence error detected within this scan (see below)
bit 29: data gap precedes this scan
bit 28: calibration anomaly detected (see below)
bit 27: earth location data not available (see below)
bit 26: first good time following a clock update (nominally 0)
bit 25: instrument status changed with this scan
bits 24 - 0: <zero fill>		 29 32
 u 4 1 0    
Scan Line Quality Flags (If a bit is on (=1) then the statement is true.)

Time Problem Code (All bits off implies the scan time is as expected.)

bits 31-24: <zero fill>
bit 23: time field is bad but can probably be inferred from the previous good time.
bit 22: time field is bad and can't be inferred from the previous good time.
bit 21: this record starts a sequence that is inconsistent with previous times (i.e., there is a time discontinuity). This may or may not be associated with a spacecraft clock update. (See bit 26, Quality Indicator Bit Field)
bit 20: start of a sequence that apparently repeats scan times that have been previously accepted.
bits 19 - 16: <zero fill>

Calibration Anomaly Code (Note these bits complement the channel indicators; all bits set to 0 indicates normal calibration.)

bit 15: scan line was not calibrated because of bad time.
bit 14: scan line was calibrated using fewer than the preferred number of scan lines because of proximity to start or end of data set or to a data gap.
bit 13: scan line was not calibrated because of bad or insufficient PRT data.
bit 12: scan line was calibrated but with marginal PRT data.
bit 11: some uncalibrated channels on this scan (see channel indicators).
bit 10: uncalibrated due to instrument mode.
bit 9: moonlight detected in space views
bit 8: <zero fill>

Earth Location Problem Code (all bits set to 0 implies the earth location was normal)

bit 7: not earth located because of bad time; earth location fields zero filled.
bit 6: earth location questionable because of questionable time code (see time problem flags above).
bit 5: earth location questionable -- only marginal agreement with reasonableness check.
bit 4: earth location questionable -- fails reasonableness check
bits 3-0: <zero fill>		 33 36 u 4 1 0    
Calibration Quality Flags (All bits off implies a good calibration.)
Word 1: Channel 1
bit 15-6: <zero fill>
bit 5: all bad blackbody counts for scan line
bit 4: all bad space view counts for scan line
bit 3: all bad PRTs for this line
bit 2: marginal blackbody view counts for this line
bit 1: marginal space view counts for this line
bit 0: marginal PRT temperatures on this line

Minor Frame Quality Indicator Bit Fields (For bits 7 through 1, if bit is on (=1) then statement is true.)

Word 1: Minor Frame 0
bit 7: this frame suspect due to a time error
bit 6: this frame contains data gap data fill
bit 5: this frame contains TIP dwell data fill
bit 4: data suspect due to PACS QC error
bit 3: mirror locked during this frame
bit 2: mirror position error during this frame
bit 1: mirror was moving during this frame
bit 0: minor word odd parity bit
