Following are the current VIIRS SDR QFs:

1.) QF1_VIIRSMBANDSDR (1byte):
    Bit0-1 -> Quality - Indicates calibration quality due to bad space view offsets, OBC view offsets, etc or use of a previous calibration view
                    (0: Good; 1: Poor; 2: No Calibration)
    Bit2-3 -> Saturated Pixel - Indicates the level of pixel saturation
                    (0: None Saturated; 1: Some Saturated; 2: All Saturated)
    Bit4-5 -> Missing Data - Data required for calibration processing is not available for processing
                    (0: All data present; 1: EV RDR data missing; 2: Cal data (SV, CV, SD, etc.) missing ; 3:Thermistor data missin)
    Bit6-7 -> Out of Rang - Calibrated pixel value outside of LUT threshold limits
                    (0: All data within range; 1: Radiance out of range; 2: Reflectance or EBBT out of range ; 3:Both Radiance and Reflectance or EBBT out of range )

2.) QF2_SCAN_SDR (1byte):
    Bit0    -> Half Angle Mirror Side
                   (0: A-Side; 1: B-Side)
    Bit1    -> The Moon hascorrupted the spaceview
                   (0: False; 1: True)
    Bit2-7 -> Spare

3.) QF3_SCAN_RDR (1byte):
    Bit0    -> Checksum failed for zone 1 (0: False; 1: True)
    Bit1    -> Checksum failed for zone 2 (0: False; 1: True)
    Bit2    -> Checksum failed for zone 3 (0: False; 1: True)
    Bit3    -> Checksum failed for zone 4 (0: False; 1: True)
    Bit4    -> Checksum failed for zone 5 (0: False; 1: True)
    Bit5    -> Checksum failed for zone 6 (0: False; 1: True)
    Bit1    -> Scan data is not Present (No valid data)   (0: False; 1: True)
    Bit7    -> Spare

4.)  QF4_SCAN_SDR  (1byte):
    Bit0    -> Quality for this scan-line is reduced. The value is determined by the combined number of steps required to find a replacement for thermistor or
                   calibration source data
                  (0: False;  >1: True)

5.)  QF5_GRAN_BADDETECTOR   (1byte):
    Bit0    -> Bad Detector - M-Band
                  (0: False;  >1: True)
    Bit1-7 -> Spare
