(meteorobs) The formulae of ZHR
Hi everyone,
I found there's difference between two formulae of ZHR, which were both
given by the IMO. Have one of them been improved?
ZHR=HR/[r^(Lm-6.5)*cos(z)^1.47] (in the calendar, and it was said it's from
IMO)
or
ZHR=(1+sum n)/sum(Teff/C)
C=r^(6.5-Lm)*F/sin(h) (in nearly all the IMO shower circular)
In the first one, the field obstruction factors F seems to be ignored.
The computational results of the two is also different. Then, which is
correct? And could someone tell me which of them I should use if I'm working
on a shower?
All best wishes and Clear skies!
