OsiCalliope Rational ATTENTION HERE! USE IMAGE HEADERS! Some products cannot be created due to: calibration (bias, dark, etc.) shutter error (no absolute calibration) missing geometry information Some images cannot be calibrated but are useful. These are generated as incomplete products: incomplete level 3 are geometrically distortion corrected but in DN incomplete level 4 are geo-referenced but in DN ATTENTION HERE! USE IMAGE HEADERS!
