They are slightly different - SIMP ignores the rates and delays in
interpolating phases from the SN table into the CL table.  However, it
will interpolate non-zero rates to the CL table in its rate column.
(See $APLNOT/SN2CL.FOR)

When DOCAL is true, any non-zero rates are used in the interpolation
of phase if the rates change between CL entries.
