-  - The SL correction use the R6 reference value and the measure SL is smoothing  using a Triangular moving average filter (see [[devel:brewerpythonmodule#sl_tma|Brewer Python Module (Triangular Moving Average)]])
+  - The SL correction uses the R6 reference value and the R6 from SL measurements smoothed using a [[devel:brewerpythonmodule#sl_tma|Triangular Moving Average]]. The correction is only applied if the difference between the two R6 values is more than 5 units.
   - The ETC filter correction is applied using the ETC correction function, the correction $ETC_N$ only affects to the measurements performed with filter #N
   - 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 following arguments are optional:
-  * Instead of ''brewerid'', you can use one of ''gaw_id'', ''woudc_id'', or ''stationid'' to request the data for a station instead of a Brewer. ''stationid'' corresponds to the internal EUBREWNET ID of the station. Note that the Brewer and station products might be different if more than one Brewer operates at a station.

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.

+  * ''onlydefaultbrewer'': When data is requested for the station, only the Brewer defined first in the [[codes:dbaccess#prioritybystation|priority list]] is used.
   * ''version'': this is EUBREWNET's processing algorithm version. If not specified, version ''1.0'' is used (note this is the only version available to the public as of April 2020)
