SDS Name: QC_Emis
Description: Emissivity Quality Indicators
Bit field legend; uint8 (Note: bit 0 is the least significant bit)
bit Long name Key
3-0 view angle flag of the 0-15, index of view angle
companion observation sub-range of the companion observation:
(which is night obs if 0-7 if view from east
LST_Day_6km valid, or (0 at the west end of scan line);
day obs otherwise) 8-15 if view from west
(15 at the east end of scan line)
6-4 time difference between 0-7 couples of days, 7 representing
day and night MODIS the range from 7 to 16
observations
7 DEM slope flag 0=DEM slope not considered
1=DEM slope considered in day/night
