DETECTOR        U16     0x0001          # Something is wrong with the detector
FLAT            U16     0x0002          # Pixel doesn't flat-field properly
DARK            U16     0x0004          # Pixel doesn't dark-subtract properly
BLANK           U16     0x0008          # Pixel doesn't contain valid data
CTE             U16     0x0010          # Pixel has poor Charge Transfer Efficiency

# Mask values which represent invalid signal ranges
SAT             U16     0x0020          # Pixel is saturated or non-linear
LOW             U16     0x0040          # Pixel is low
SUSPECT         U16     0x0080          # Pixel is suspected of being bad

# Mask values which represent non-astronomical structures
BURNTOOL        U16     0x0080          # Pixel may contain uncorrected streak.
CR              U16     0x0100          # Pixel contains a cosmic ray
SPIKE           U16     0x0200          # Pixel contains a diffraction spike
GHOST           U16     0x0400          # Pixel contains an optical ghost
STREAK          U16     0x0800          # Pixel contains a streak
STARCORE        U16     0x1000          # Pixel contains a bright star core

# Mask values which identify pixels badly affected by convolutions and interpolations
CONV.BAD        U16     0x2000          # Pixel is bad after convolution with a bad pixel
CONV.POOR       U16     0x4000          # Pixel is poor after convolution with a bad pixel

# Spare value for temporary marking
# MARK          U16     0x8000          # Pixel is temporarily marked
