Time Series Folding Reference Point #44

Closed JackActon closed 5 years ago

JackActon commented 5 years ago

The FoldAt command;

PyAstronomy.pyasl.foldAt(time, period, T0=0.0, getEpoch=False)

Takes the input T0, described in the documents as a reference point. I'm folding some time series data of my own, with a known period and epoch. Is there any way of knowing what this reference should be?

Thanks.

Hi,

as far as I understand your description, T0 corresponds to what you call "epoch". That point would be mapped to phase zero.

Cheers

Hi,

Okay, so just for future knowledge. Is the 'Reference Point' just the point that the folding will map to phase 0 then?

Thanks.

Yes. And all points given by T0+n*period with integer n likewise. I updated and extended the docu, which should no hopefully be clearer.
