   - The Stray Light ETC filter correction as depend of he ozone is an iterative process, in most cases only one iteration is needed (OSC<1600 DU) and is enough with two iterations for all the cases (up to OSC 2000DU). On the database two iterations are defined by default.   - The Stray Light ETC filter correction as depend of he ozone is an iterative process, in most cases only one iteration is needed (OSC<1600 DU) and is enough with two iterations for all the cases (up to OSC 2000DU).
