It's very small 'taters, as we Hoosiers are apt to say. The thing is, though, it's also deterministic, and subject to being modeled, characterized, and compensated for. And for what we're using this collimator for, that compensation must be regarded as a required exercise. Even though it's small 'taters, we're obliged to keep the best track we can of every single little-bitty fraction of every single 'tater.<br /><br />Mmmmm, and now I'm hungry for something starchy. My own fault, too.

The <em>half-percent subtleties of geometric distortion in a three-mirror anastigmat test collimator</em> that you left us for might disturb my sleep.

Might as well find out if that's still a problem.Jim Wetzelhttps://www.blogger.com/profile/07358539074647113747noreply@blogger.comtag:blogger.com,1999:blog-9748383.post-21103839297952323632009-12-21T19:56:33.943-05:002009-12-21T19:56:33.943-05:00Post, don't post, it's up to you.

It seems to swirl in an ever-tightening orbit of the toilet bowl.<br /><br />PS: the CAPTCHA I'm asked to verify is "perearse". If I were you, I'd ask Blogger to keep kid's butts out of their system.Dr. Harl Deloshttps://www.blogger.com/profile/17424071404764987713noreply@blogger.com
