fiducial_positions_20220916.csv is renewed position. 

Either cloomis or hassan , could you please upload to Github, after checking?

I propose doing the same thing as for black dots and xml files: rename the existing `fiducial_positions.csv` to `fiducial_positions_20210524.csv`, add the new file as named, and add a symbolic_link to the new file from `fiducial_positions.csv`: a cheap way to make the history both explicit and available.

[ and the new name should of course be 20220916 instead of 20210916.... ]

It sounds a good idea.

And I replaced the file by correcting the date.

By the way I have one question: should we renew dot position, at least initial position for re-measurement?

cloomis my apologies, Hassan double checked my position and found discrepancy. After discussion, we think fiducial_positions_20220916c.csv is the one to be used. 

I'm very sorry for bothering you (I was in too rush). Could you replace the file? (you could omit "c" on the repository, as precious one was wrong.)

The new file has been linked on shell-ics, so I close this ticket (again).

For recordings: the formula of the transformation is as follows:

dX = -1.748 # mm
dY = -0.963 # mm
dT = +0.684171 # deg
dS = 1.000111458 # scale ratio

xx = x_old + dX
yy = y_old + dY

x_new = dS*cos(dT)*xx - dS*sin(dT)*yy

y_new = dS*sin(dT)*xx + dS*cos(dT)*yy
