Hello,
I’m amazed by the performance of the `fastnifty` method for Lomb-Scargle analysis, and I have started to use it everywhere for LSST analysis (with millions of periods to extract)! I was wond…

I was browsing astropy today and came across a multiband version of the Lomb Scargle periodogram. I was wondering if Stingray could use multiband functionality in not just the Lomb-Scargle periodogram…

I am attempting to compute a spectral window by taking the power spectrum of ones sampled as the time series. I expect a value of 1 at frequency=0, but usually I get zero power at zero frequency... b…

I've previously used astropy for Lomb Scargle Periodograms and I was curious what implementation lightkurve uses? I tried to add False alarms to the plots but the ls object doesn't appear to have the …

1. Need to provide a reminder of what PDCSAP means
2. Link commands to API
3. Make clear that there are other methods to find the period and explain what the Lomb-Scargle Periodogram is.

At the AAS230 Hack Day, @jenawhit, @kelle, and others worked on a tutorial incorporating K2 data. Highlights of the tutorial include:
- the *awesome* astropy progress bar
- astroML time series Lom…

I'm currently poking around in some data using gatspy, and wanted to take a stab at calculating some false-alarm probabilities. It took me a while of reading the gatspy source code to figure out that …
