| 144 | |
|---|
| 145 | <h4>Restrictions</h4> |
|---|
| 146 | U and V matrices can be 2 or 4d. |
|---|
| 147 | Beware, to discern different configuration of U and V (xy, xyz, xyt, xyzt), |
|---|
| 148 | we look at the variable of the common |
|---|
| 149 | -time which contain the calendar in IDL julian days to which U and |
|---|
| 150 | V refered to, in the same way as the variable |
|---|
| 151 | -jpt which is the number of time's step to consider in time. |
|---|
| 152 | U and V arrays are cut in the same geographic domain. Because of the gap of |
|---|
| 153 | T, U, V and F grids, it is possible that these two arrays has not the same |
|---|
| 154 | size and refered to different indexes. In this case, arrays are re-cut on |
|---|
| 155 | common indexes and the domain is redefined to match with these common |
|---|
| 156 | indexes. To avoid these re-cuts, use the keyword /memeindice in domdef.pro |
|---|
| 157 | |
