   - 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).

The files downloaded with ''brewerid'' and ''woudc_id'' are slightly different. When downloading by station, data from other Brewers may be included—such as in following case, where data from Brewer #185 is included for 2019-01-20. Brewer selection is based on the [[codes:dbaccess#prioritybystation|brewer priority configuration]] for each station.
