A Happy New Year.
The dither alignment scripts did not run on linux machines because tdscntr and ezcademod do not run
on linux. Tobin wrote a perl version of tdscntr and I modified it for 40m some time ago.
Today, I wrote a perl version of ezcademod. The script is called ditherServo.pl and resides in /cvs/cds/caltech/scripts/general/.
It is not meant to be a drop-in replacement, so the command line syntax is different. Usage is explained in the comment of the script.
Using those two scripts, I wrote linux versions of the alignment scripts.
Now when you call, for example, alignX script, it calls alignX.linux or alignX.solaris depending on the OS of
your machine. alignX.solaris is the original script using the compiled ezcademod.
In principle, ezcademod is faster than my ditherServo.pl because my script suffers from the overhead of
calling tdsdmd on each iteration of the servo. But in practice ditherServo.pl is not that bad. At least, as far as
the alignment is concerned, the performances of the both commands are comparable in terms of the final arm power and the convergence.
Now the alignXXX commands from the IFO Configure MEDM screen work for X-arm, Y-arm, PRM and DRM. I did not write a script for Michelson, since
it is optional.
I confirmed that "Align Full IFO" works correctly. |
