EOF - gaussian grid

Hi everyone.

I'm using the eof_1.ncl script, but I have one problem. The problem occur
in these commands:

;==========================================================
; create weights: sqrt(cos(lat)) [or sqrt(gw) ]
;==========================================================
  rad = 4.*atan(1.)/180.
  clat = f->lat
  clat = sqrt( cos(rad*clat) ) ; gw for gaussian grid

;==========================================================
; weight all observations
;==========================================================
  wSLP = SLP ; copy meta data
  wSLP = SLP*conform(SLP, clat, 1)

I can believe that the problem is because my grid is gaussian, and I do not
use gw, but I do not know what is gw.
