This function creates a new array section which refers to a selected region of an existing array (or array section). The section may be larger or smaller in extent than the original array.

void arySect( Ary $\ast$ary1, int ndim, const hdsdim $\ast$lbnd, const hdsdim $\ast$ubnd, Ary $\ast$$\ast$ary2, int $\ast$status )

• The number of section dimensions need not match the number of dimensions in the initial array. Pixel-index bounds will be padded with 1’ s as necessary to identify the pixels to which the new section should refer.

• Note that sections which extend beyond the pixel-index bounds of the initial array will be padded with bad pixels.

• If this routine is called with " Status" set, then a value of NULL will be returned for the " ary2" argument, although no further processing will occur. The same value will also be returned if the routine should fail for any reason.
