+By default, diagnostic output files are written in NetCDF format but an IEEE binary output format, called DIMG, can be chosen by defining \key{dimgout}. 
 
 Since version 3.2, when defining \key{iomput}, an I/O server has been added which provides more flexibility in the choice of the fields to be written as well as how the writing work is distributed over the processors in massively parallel computing. The complete description of the use of this I/O server is presented in the next section.

+\section{25 hour mean output for tidal models }
+
+A module is available to compute a crudely detided M2 signal by obtaining a 25 hour mean.
+The 25 hour mean is available for daily runs by summing up the 25 hourly instantananeous hourly values from
+midnight at the start of the day to midight at the day end.
+This diagnostic is actived with the logical  $ln\_dia25h$

+\section{Top Middle and Bed hourly output }
+
+A module is available to output the surface (top), mid water and bed diagnostics of a set of standard variables. 
+This can be a useful diagnostic when hourly or sub-hourly output is required in high resolution tidal outputs.
+The tidal signal is retained but the overall data usage is cut to just three vertical levels. Also the bottom level 
+is calculated for each cell.
+This diagnostic is actived with the logical  $ln\_diatmb$
