Programming language: Fortran.
Operating system: UNIX.
RAM: 14M words
Keywords: Elementary particle physics, QED, Electron-positron collision, Radiative return, Anomalous three gauge boson couplings.
Classification: 11.4.

Nature of problem:
Precise cross sections of hard photon productions with missing energy. Study of anomalous triple-gauge-boson couplings at LEP-2.

Solution method:
The exact matrix elements of single- and double-photon emission, generated by the GRACE system, are convoluted with the QED parton shower (QEDPS) to deal with the initial state radiations (ISR).

Convergency of the integration may be bad when inappropriate experimental cuts are applied.

Unusual features:
When errors of the integration are greater than several percent even with more than 10 M sampling points, please contact the authors.

Running time:
1 hour.
