Dear Users,

1. The next version adds two new keyword FB1 and FB2 for BEND. These are used to specify F1 at the entrance and exit separately. Actually (F + FB1) and (F1 + FB2) are used at the entrance and the exit, separately. Some geometrical inconsistency with unequal FB1 and FB2 is just ignored.

Dear Users,

1. Some inconsistency in the radiation calculation associated with the introduction of FB1 and FB2 was corrected. Also a few corrections in the coding were made by A. Morita.
