Inaccuracy in the registry.chem file

[encyclica]

In the Registry in the 'Registry/registry.chem' file there are such lines:

state real setvel_1 ij misc 1 - r "setvel_1" "dust gravitational settling velocity for size 1" "m/s" state real setvel_2 ij misc 1 - r "setvel_2" "dust gravitational settling velocity for size 2" "m/s" state real setvel_3 ij misc 1 - r "setvel_3" "dust gravitational settling velocity for size 3" "m/s" state real setvel_4 ij misc 1 - r "setvel_4" "dust gravitational settling velocity for size 4" "m/s" state real setvel_5 ij misc 1 - r "setvel_5" "effective gravitational settling velocity for total" "m/s"

All experienced users know that all 5 bins of the dust aerosol are independent. So description of the "setvel_5" variable ("effective gravitational settling velocity for total") is misleading inexperienced users.

In WRF-Chem in the 'chem/module_gocart_settling.F' source file (where these variables are defined) all setvel variables are using in the same manner. "setvel_5" variable does not stand out with anything.

I am sure that this line should be changed to: state real setvel_5 ij misc 1 - r "setvel_5" "dust gravitational settling velocity for size 5" "m/s"

I think current variant is outdated for a very long time.
