olp v7.0 introduces the empirical photometric correction of chopped measurements. the correction factors were established by comparing chopped measurements against staring measurements. for stability arguments these calibration measurements were restricted to one filter each. furthermore the chopped photometric correction introduces the concept of orbit dependent default responsivities. as there are no multi-filter reference measurements both in staring and chopped mode available, this proposals closes the gap.

Mission Description
The Infrared Space Observatory (ISO) was the worlds first true orbiting infrared observatory. Equipped with four highly-sophisticated and versatile scientific instruments, it was launched by Ariane in November 1995 and provided astronomers world-wide with a facility of unprecedented sensitivity and capabilities for a detailed exploration of the Universe at infrared wavelengths.
