[gvSIG_Italian] Peakflow output

Mar 28 Ago 2018 02:35:26 PDT

Ciao Niccolò,
credo che la differenza sia dovuta a due modi diversi di calcolare la
portata massima, ovvero nel log vedi il calcolo diretto nell'istante esatto
del massimo, mentre nel CSV il calcolo è fatto rispettando gli intervalli
di tempo indicati. E' anche normale che ci siano intervalli un po' diversi,
in realtà sarebbero arrotondati... ma lo puoi fare a mano.
