15#!N #!N Functional Details #!N #!N Reduces the resolution of regularly
16connected grids. Box filtering is applied to minimize aliasing effects in
17the components that are associated with the grid. It filters and
18reduces the number of items in the "data" component of the
19input field and also in any components that are position or
20connection dependent. #!N #!I0 #!N #!N #!I0 #!N  #!F-adobe-times-bold-r-normal--18*    #!F-adobe-times-bold-r-normal--18*   input
21#!EF #!EF #!I50 #!N is the field to be reduced. It
22must have regular connections. #!N #!I0 #!N  #!F-adobe-times-bold-r-normal--18*    #!F-adobe-times-bold-r-normal--18*   factor #!EF
23#!EF #!I50 #!N specifies the reduction factor(s) to be used in
24reducing the resolution of the field. #!I0 #!N #!N If this
