LcTools for Data Mining TESS, K2, and Kepler Light Curves

Hello Everyone,

For those of you wishing to data mine light curves from the TESS, K2, and Kepler missions, you might want to consider using LcTools, a large-scale Windows based software system for viewing and analyzing light curves. The system is optimized for processing large numbers of light curves in a fast and efficient manner to facilitate data mining activities.

The LcTools system consists of four major applications -- LcGenerator, LcSignalFinder, LcViewer, and LcReporter.

  * LcGenerator builds light curve files in bulk for use with LcSignalFinder and LcViewer. A typical batch consists of 25,000 to 50,000 files.

  * LcSignalFinder automatically detects and records signals found in a large batch of light curve files either produced by LcGenerator or downloaded from the LcTools website. Signals may be periodic or non-periodic, dips or peaks of any type. The most common types of signals are eclipsing binaries and planetary transits.

  * LcViewer plots light curves graphically and finds, records, measures, displays, and phase folds signals of interest. Using a work group, light curve files can be loaded quickly at the press of a key or button to rapidly iterate though a large batch of files for viewing purposes.

  * LcReporter produces an Excel report listing the user defined signals recorded by LcViewer.

In conjunction with the software, data assets may be downloaded from the LcTools website. Data assets include star list files for use with LcGenerator and pre-built light curve files in large batches for use with LcSignalFinder and LcViewer. Currently for the TESS mission, over 2 million light curve files are available for download in batches of 25,000 files (approx.).

Both the software and data assets are free for registered LcTools users. For more information on the system, see the published research paper and the LcTools Product Description. To request the product for use, please contact me at

Thank you for your time.

This looks awesome! Much

This looks awesome! Much easier to use a program that makes it easy to get all the files in one place.

I'll have to get a PC (I'm a Mac user) setup soon and give it a shot.

Thanks for the awesome new tool!
