|---|
| 15 | c Target points are on a rectangular grid: |

|---|
| 17 | c jjm+1 longitudes, with periodicity jjm+1=1. |
|---|
| 18 | c aux poles. At the poles the fields value is repeated |
|---|
| 19 | c jjm+1 time. |
|---|
| 20 | c The parameters a,b,c,d represent the limite of the target |
|---|
| 21 | c gridpoint region. The means over this region are calculated |
|---|
| 22 | c from USN data, ponderated by a weight proportional to the |
|---|
| 23 | c surface occupated by the data inside the model gridpoint area. |
|---|
| 24 | c In most circumstances, this weight is the ratio between the |
|---|
| 25 | c surface of the USN gridpoint area and the surface of the |
