COMMENT:
//
// This Helicity was added to remove confusion with NCEP or model
// calculated 0-3km Helicity and the D2D/VB calculated Helicity.
// 0-3km Helicity would display as Surface Helicity if delivered
// from NCEP if no changes are made to the baseline. This change
// works with the Heli field further below in this file.
// HeliD is SR Helicity made from model post-processing,usually NCEP.
// Heli is now the SR Helicity, for the layer and model chosen,
// and calculated via VB code
// using Bunkers et. al. storm motion.
// IF YOU ADD this field, you should also add Heli and EHI
// in the nationalData replacement section below.
