Re: [ferret_users] Axis extremes

[Ryo Furue <furue@xxxxxxxxxx>]

Hi Ferret users,

I kind of agree with Tony.  Logic tells us that

| let dLW=(tdt_lw[d=2]-tdt_lw[d=1])
| 
| !These commands works:
| 
| fill/z=500/l=1 dlw
|  *** NOTE: Ambiguous coordinates on T axis: (TDT_LW[D=2]-TDT_LW[D=1])
| fill/z=500 dlw[l=1]

if the above works,

| !But these don't!
[. . ]
| fill/z=500 dlw[l=1:12@ave]
|  **ERROR: illegal limits: TDT_LW is not in the range T=01-JAN-2040
| 18:00:31-DEC-2040 18:00
|           Axis extremes are T=01-JAN-2000 18:00:31-DEC-2000 18:00

then this one "should" work, too.

The indices i, j, k & l denote positions within an array without
referring to the physical, spatio-temporal positions.  Therefore,
whether the physical positions match or not doesn't matter . . .
Or is there more to it?

Regards,
Ryo
