Periodfind
Minor feature update.
Changes
Python API:
- Added new option "center" to calc method of periodogram classes.
- This new option shifts the magnitude data so it has zero mean. Defaults to true for Lomb-Scargle, and false for other algorithms.
- Outputs from Lomb-Scargle may be different with this release by default. Setting center=False will revert to the old behavior.
- New outputs from Lomb-Scargle are likely the expected outputs in cases where input data does not already have a mean of zero.
