The specMACS VNIR shutter has been inoperative (stuck in open position), therefore darkcurrent for the VNIR must be estimated. In the VNIR quicklooks, this is visible as a blueish color, as the estimation is currently not implemented.
The system which is responsible for dark current measurements is also responsible for autoexposure. Therfore, the integration time has not been adapted throughout the flight which in turn caused some over exposure events which otherwise could have been prevented.
