Problem with bender component

[Stuart Rycroft]

Hello

I just wanted to mention a problem with the bender component, which can be
downloaded from the Riso or ILL website.  They both have an early version
of the component (Feb. 7th 1999) but from the email archive, a later
version (Feb. 22nd 1999) was sent by the author (Philipp Bernhardt) which
corrects a small bug in the calculation of the reflectivity for the top
and bottom mirrors.  Without this correction the output from my simulated
guides is obviously not correct when looking at the divergence, but it is
very hard to see a problem when just looking at an intensity since the
only effect I have seen is a small loss, maybe around five percent. 

The updated component and the problem are given by the author in the
mailing archive:

Maybe the component list on the Mcstas webpages should have this version
instead of the old one.
