[vsnet-chat 3854] re wavelet analysis software

[crawl@zoom.co.uk]

well, I'll go to the foot of our stairs...


It appears that the wavelets program is still available.  Urlificate
thuswards: http://vsnet.aavso.org/adata/software.stm , and you want wwz11.zip
and the readme noted just below it... ...oh, and a strong stomach.  Wavelet
analysis is not for the weak at the knees. It is also damn slow [especially
under DOS], and may require overnight runs for meaningful stepsizes and
substantial datasets.

I'll have to note, as with much aavso stuff, that if you use this computer
program for anything you have to credit aavso all over the place in any
publication you may manage, though in my personal opinion the statement
listed there that "Published works using the WWZ should refer to the
following article: Foster, G. 1996, AJ, 112, 1709" should be all that is
necessary, and is actually technically necessary, for it is indeed the
paper containing details of the mathematical procedure that has been used
by Foster.  I will not confess to even remotely understanding it, but that
don't stop you using it as a "black box", for the input data and the output
data are easy enough to use and understand.
