- Simon submitted changes reflecting the time-to-distance calculations. He uses Mike's table with the wire-tube offsets (as extracted with cosmics) to re-calculate the  time-to-distance function (with field off and on), as he reported last week. Mike is checking the new calculations for curved tracks.

- Mike: applying deformation corrections improves the CDC resolution to its design value of ~150 microns. This was demonstrated in his talk at the DNP meeting.

- Lubomir almost finished converting his code with specialized FDC alignment/efficiency calculations into a plugin that runs with the standard halld analyzer. One important difference is that the multi-hit feature present in the original code could not be preserved in the pluging - halld analyzer assumes only one hit per channel. Still the resolutions obtained with the plugin are very similar to those with the original code. Some tweaks had to be made in the emulation code, as well. The plugin produces 3D hits (points) using both cathode (amplitude) and wire (timing) information. We will work on an interface that passes these points to Simon's tracking.
