I thought that superwasp used some type of transformation and that for this reason there was no light curve like Kepler. Now I understand the plots better, thank you very much !!

<p>I am trying to plot superwasp lightcurves in python from the fits files, using TMID and FLUX2, getting this:</p>

What is your question? What is on the axes?

Not sure what you are expecting to see from the two datasets. Both datasets are examples of light curves, flux against time with different arbitrary origins for the time axis; SuperWASP `TMID` is integer seconds from Julian Date 2453005.5, Kepler uses BKJD = Barycentric Kepler Julian Date, but offset by 2454833.0. i.e., BKJD = BJD - 2454833.0. The SuperWASP datasets typically span 4 years (it's a little difficult to read the plot scales of the example) and are from a ground-based set of small (11.1 cm diameter) lenses with a CCD and so will have day gaps and weather. Kepler/K2 data are from a space-based 95cm telescope which was able to stare at the same patch of sky continuously for about 90 days before a break (and of course had no weather). Consequently there will be a considerable difference in appearance and photometric precision of the lightcurves.

[This page](https://exoplanetarchive.ipac.caltech.edu/docs/API_superwasptimeseries_columns.html) at the NASA Exoplanet Archive gives details on the SuperWASP public data and [this Python Jupyter notebook](https://github.com/spacetelescope/notebooks/blob/master/notebooks/MAST/K2/K2_Lightcurve/k2_lightcurve.ipynb) has info on plotting K2 light curves.
