Should we repeat any measurements with the current set up of the CCD mount and mirror resting on the table? Also, when would the mirror stand that Marco Mirazita took back to INFN return to JLab so we can repeat the d0 measurements with a more stable stand? Please let us know.<br data-mce-bogus="1"></div><div><br data-mce-bogus="1"></div><div>Best regards,<br data-mce-bogus="1"></div><div>Tyler<br data-mce-bogus="1"></div></div></body></html>
