W. Trevor King [Fri, 27 Mar 2009 13:17:36 +0000 (09:17 -0400)]
Reposition cantilever between each bump to adjust for piezo creep.
W. Trevor King [Tue, 10 Feb 2009 18:07:48 +0000 (13:07 -0500)]
Updated documentation for calibcant.calibrate.calib_aquire.
W. Trevor King [Wed, 28 Jan 2009 13:43:54 +0000 (08:43 -0500)]
Removed old references to freq in calibrate.py after freq->push_speed change.
Also turned plotting back on by default (the change doesn't affect
command line usage).

Start bumps with the cantilever _off_ the surface.
Photodiode sensitivity (and thus, bump slope) decreases as the
zero-deflection photodiode input moves away from zero Volts. In order
to mitigate the effect of this on our calibration, we need to keep
track of the zero-deflection signal. By starting our bump off the
surface, our bumps should always start and end in the zero-deflection
regime.
This will make analysis a bit more complicated though. I'll get to
that next.

Control bump_speed instead of bump sample frequency.
More physically useful number. The old default speed was huge.

Prepared for distribution.
Fixed lines in the Makefile that I hadn't changed when I copied it into
this project in the beginning. Also added GPL blurbs to two py files.

New Marisa/me calibration difference bug

W. Trevor King [Sun, 21 Dec 2008 05:12:00 +0000 (00:12 -0500)]
Apply some fixes to get calibrations working and bump version.
Mostly namespace problems due to `from numpy import *` and the
like. Things seem to work now. I think we're ready for prime-time.
W. Trevor King [Sun, 21 Dec 2008 05:01:11 +0000 (00:01 -0500)]
calibrate.py should now work.
A bunch of changes in one commit, sorry.
Moved to fledgling splittable_kwargs system to make default argument
maintenance easier. I expect the splittable_kwargs system still has
some growing to do, but it's already better than the old system.
Merged BE database from the calibcant subdir into the main BE database.
It was a mistake to create the database there in the first place.

Began versioning.
