Folding
ASTERIX contains three folding routines, FOLDLOTS, FOLDAOV and
FOLDBIN. FOLDLOTS is a standard period search technique and can
be used on any dataset. FOLDAOV uses the analysis of variance
technique which is theoretically superior at detecting sharp
periodic signals in small sample datasets. Finally if the period
is known, FOLDBIN, will fold an N-dimensional dataset at a given
period.
