[ferret_users] Axis extremes

[Jian Ma <jianma@xxxxxxxxxx>]

Hi All,

When I do calculations among variables with different time axes, even if
I already set the time mean (l=@ave), ferret still don't allow because
the variables have different axis range. How to make this error silent? 

Currently I am using gt=@asn but feel it stupid and messy. Does anyone
have a better solution?

Many thanks,
Tony
