Re: [VLF_Group] www.vlf.it update
extracted from tweeks.
Some while ago I made some trials with vttoga to get it to
recognise tweeks and measure their tails. Was hoping the
TNU group could use it to automate their measurements but
the program wasn't reliable enough. Both the recognition and
the measurement are tricky to do and easily upset by noise,
sferics and mains harmonics. It is hard to do better than
manually placing a cursor on the tail by eye.
The code remains in vttoga with an undocumented -w option,
uses a spectrum reassignment to try to pick out the
asymptotic tail frequency. One day I'll get back on to
- Two new updates are available on the website www.vlf.it:
The IdealLoop project is now also equipped with a PCB, thanks the work that Jochen Richert has agreed to share to all:
The part is added to the end of 2014 Article.
As part of OPERA monitoring project, an event, that shows what were received our monitoring stations during the gravitational wave passing detected by LIGO, has been added .
