[Halld-cal] Module 45 fibres

[Zisis Papandreou]

Hi Elton:

I had a look at the photo on Mod 45.  You can also view it from the Travellers page:

(click on Mod 45 and then End 1 Image)

In this photo it is hard to see many fibers that appear darker than their neighbours, although there are a handful.  Some of the ones that showed up in your picture unfortunately are in the zone covered by the ruler in our photo.  The appearance of such differences is to some extend a function of the viewing and illumination angle.  I can't find any more photos from this module -- they are probably on Danny's desktop.  If it is pressing I can try to retrieve them.

In the meanwhile, please keep informing me of such defects.  For other modules we had many more pictures, but at the end we took fewer.  Always, we inspected things by eye and if anything appeared out of the ordinary we took many pictures from different angles.  Nothing stuck out when inspecting Module 45.

Cheers, Zisis...
