o switch from Airy functions
to sines and cosines in piecewise method.  Default is 1000 fm.

AJSWITCH - default is 0.0

<BR>
Normally the Coupled Coulomb wfns are matched to zero
and the Numerov integration is omitted,
when the Coulomb distance of closest approach is more than 4.5 fm outside
abs(RMATCH) (or  the  -CUTR distance if   CUTR negative).
This is only allowed when <!-- MATH
 $J_{total} \geq$
 -->
