[ferret_users] shifted longitude problem with scat2gridgauss_xy

[Lev Tarasov <lev@xxxxxxxxxxxxxxxxxxxxxxxxxx>]

Hi;

Given

DEFINE AXIS/X=1:2000:1 xin
DEFINE GRID/X=xin  gin
FILE/SKIP=1/VAR="cn,ylt,xln,bedRfr,tillcode" /GRID=gin NOR_2212DriftThickKleman.dat

DEFINE AXIS/X=0.25E:119.25E:0.5/UNIT=DEGREE xlone5fb
works for
LET bedR1 = scat2gridgauss_xy (xln,ylt, bedRfr[d=1], x[gx=xlone5fb], y[gy=ylate25f], 0.5,0.5, 0.9,0)

but
DEFINE AXIS/X=4.75W:119.25E:0.5/UNIT=DEGREE xlone5fb
shifts the data eastward about 10 degrees.

And I need to grid to a Longitude grid that crosses 0 Longitude.

I'm using         FERRET v5.81,         Linux(g77) 2.4.21-32 - 07/14/05

How do I fix this? It's a problem I've run into the past as well, and
have crudely just shifted the input longitudes in scat2gridgauss_xy but
I'm hoping a better fix is available.

thanks,

Lev
