Dear Ferreters,
I wonder if anyone can reproduce the behaviour that when I average a
variable beyond its time axis limit in time, I get a non-invalid,
rather than invalid field. Here is an reproducible example:
$ ferret -nojnl
NOAA/PMEL TMAP
FERRET v6.4
Linux(g77) 2.6.9-89.ELsmp - 11/30/09
5-Aug-10 14:23
yes? use monthly_navy_winds.cdf
yes? show data
currently SET data sets:
1>
/home/dwang/software/ferret/fer_dsets/data/monthly_navy_winds.cdf
(default)
name title I J
K L
UWND ZONAL WIND 1:144 1:73
... 1:132
VWND MERIDIONAL WIND 1:144 1:73
... 1:132
yes? shade uwnd[l=133]
**ERROR: illegal limits: UWND does not exist at L=133
Axis extremes are L=1:132
!!! Ferret correctly points out l=133 is out of axis limit.
yes? shade uwnd[l=133:144@ave]
!!! Ferret shows a map. But l=133:144 is out of axis limit! The time
axis is not a modulo axis.
This is Ferret 6.4 on a 64-bit Linux box.
Thanks,
David
