no STDEVBIRD check when converting reflectivity to bird density

[jspaaks]

• reference code
• what I think should be the place to add it

Would it be possible to manage including/excluding of certain gates based on another flag using the includeGate() and classifyGatesSimple() methods?

Question @adokter: what does it this check do conceptually?

Indeed this is the right place to add it, however you need output from svdfit that is now coded only at a later stage.

The following steps are needed:

1. Take the chi that you calculate here for iProfileType==3.
2. When you calculate the bird density here for iProfileType==1 , all bird densities should be set to zero when chi<STDEVBIRD.

Conceptually, this is the most important classification step between birds and particles passively tracing the wind field, such as most insects and precipitation. Only birds cause a high chi.

Here's what I propose. I'll change the program to always calculate 3 profiles but in a different order: 3, 2, 1 rather than 1, 2, 3. When I'm calculating iProfileType==3, I can fill an int array list with nLayers elements, with either TRUE or FALSE values, depending on the result of chi<STDEVBIRD. This array can then later be used when processing iProfileType==1. Sounds good?

Sounds good!
