INCHWORM, written by N. Elias II, is not part of the
software, but we document a few instructions here on how to use it.
To create a .inch file from a .con file, startup INCHWORM and then type inchworm inch1 /gemini/npoi/con/2003-03-15.con -dir. You can delete the inch1 object by typing inch1 delete.
Then open the file and go to RawScanData, double click on sid 1,
and go to Edit
De-glitch. In this widget deselect tuple (1,2,4)
and (1,3,5), and then click on Find. Fix every glitch listed by
double-clicking the glitch and then, judging by the plot, the laser
which glitched. Select this laser (Calc) and click Fix.
Note that lasers 2&4, as well as 3&5 are degenerate since they are
180 degrees apart. Also, lasers 2&5 and 3&4 are on the same side of
the plate and should therefore move in the same way. You do not have to
work on the glitches in sequence, but note that of course every fix will
shift all laser values from current to end by that amount. Typically,
there is up to a three count difference between calculated and predicted
values of the glitch. 100 counts = 0.5
m. Any notes can be entered
into the INCHWORM log using View|Logs|InchwormLog.
After fixing all glitches, go to Average, (Re)createScanData, then Calculate
By Time, then Calibrate and then Done.
To prepare the motion group, go to Motion, )(Re)createGo,
Calculate, Calculate, Done, Done. To exit,
go to File
Done.
