If this card is present, real phase shifts rather than complex phase
shifts will be used. The results of the calculation will not be
accurate. This option is intended to allow users to obtain real
scattering phase shifts for use with other programs, or for
diagnostic purposes. The phase shifts can be written to output
files `phaseNN.dat' using the PRINT card.
If the RPHASES card is present, these will contain the real phase shifts.
