This field is a 1 byte, bit-packed field, where the first 4 bits represent contain the bin-level validity information, and the next 4 bits are the measurementlevel validity information. When the data is valid, this field will be 0. Bit 1: Overall validity. Data invalid 1, otherwise 0; Bit 2: Bin-level validity spare. Default 0; Bit 3: Data saturation found 1, otherwise 0; Bit 4: Data spike found 1, otherwise 0; Bit 5: Measurement-level validity spare. Default 0; Bit 6: Source packet invalid 1, otherwise 0; Bit 7: Laser Frequency not locked 1, otherwise 0; Bit 8: Spacecraft attitude not on target 1, otherwise 0
