TESS QLP Stars Observed in Multiple Sectors
Part I. Introduction
This document describes how to install a TESS QLP multi-sector star list file and then use it to build a TESS QLP light curve directory with LcGenerator. Only stars observed at a 30-minute cadence or at a 10-minute cadence are available in a star list file. Stars observed at a 2-minute cadence or at a 20-second cadence are omitted.
In order to build a TESS QLP light curve directory with LcGenerator, LcTools V18.3 or above is required. If you have any questions, please contact the LcTools author at aschmitt@comcast.net.
Part II. Installing a TESS QLP Multi-Sector Star List File
1. Using the tables below, find the multi-sector star list file you wish to install. Right-click on the file and select “Open link in new window” from the pop-up menu. Move the window so you can still see these instructions.

2. You will be taken to Google Drive on the Web. Click on the Download icon located in the top right corner of the page. The icon should look like this:
3. Once your Web browser has downloaded the star list file, click on the file to open it in Notepad. Keep the file open. You will use it later in the process.
Part III. Using LcGenerator to Build a TESS QLP Light Curve Directory
1. Start LcGenerator.
2. In the "Lightcurve Directory" field, type-in the full pathname of a new QLP light curve directory. Any target drive or folder may be used. For example "C:\Lightcurves_TESS_QLP_North_13_Sectors".
3. In the Project field, select TESS_QLP from drop-down list.
4. Under the "Star List File" field, click the Select button. In the subsequent dialog box, right-click on file "Stars.txt" and select Edit from the pop-up menu. File "Stars.txt" will be opened in Notepad for editing.
5. In the multi-sector star list file that you opened in Part II step 3, select a range of star IDs for the light curve files to build. Limit the number selected to about 50,000. More than that may cause performance or usability issues in LcTools.
6. Copy and paste the selected star IDs into file "Stars.txt" that was opened in step 4.
7. Save file "Stars.txt" under the same filename then close Notepad.
8. Click the Open button in the same dialog box that was opened in step 4.
9. Close the multi-sector star list file.
10. In the Periods group box, select the All radio button to select all available sectors.
11. Select an applicable cadence (Long or Short). Long is the default. If Short is selected, choose a bin size from the drop-down list. If you intend to run LcSignalFinder later on, a value of 2 points per hour is recommended.
12. Select an applicable quality filter. For optimal results, the second button is strongly recommended.
13. Click the "Start Job" to begin building the light curve files in the specified directory. A sample LcGenerator window is shown below:
See the "LcGenerator User Guide" for details. The document can be opened within LcGenerator by selecting "Help→User Guide" from the menu bar.
14. While the job is executing, you can use LcViewer to view the light curve files built thus far by LcGenerator. See section "Using Work Groups" in the "LcViewer User Guide". The document can be opened within LcViewer by selecting "Help→User Guide" from the menu bar.
