It is taken with the fore-optics shutter closed and recorded without any on-board subtraction performed (the same values are recorded every major frame throughout a flight line). This data is subtracted from the image data onboard the aircraft during a flight line in order to keep the image signal level on scale in the signal chain. It is also onboard subtracted from the dark current measurements taken during a flight line." /* Description of objects */ OBJECT = SPECTRUM_HEADER BYTES = 896 RECORDS = 2 TYPE = VICAR2 ^DESCRIPTION = "VICAR2.TXT" END_OBJECT = SPECTRUM_HEADER OBJECT = SPECTRUM INTERCHANGE_FORMAT = BINARY ROWS = 512 ROW_BYTES = 448 COLUMNS = 1 SAMPLING_PARAMETER_NAME = WAVELENGTH SAMPLING_PARAMETER_UNIT = MICROMETER MINIMUM_SAMPLING_PARAMETER = 0.3947 MAXIMUM_SAMPLING_PARAMETER = 2.4501 SAMPLING_PARAMETER_INTERVAL = 'N/A' OBJECT = COLUMN NAME = DARK_CURRENT_OFFSET DATA_TYPE = VAX_INTEGER START_BYTE = 1 BYTES = 2 ITEMS = 224 END_OBJECT = COLUMN END_OBJECT = SPECTRUM END
