Embedded Files
Part I. Introduction
This document describes how to install a TESS CTL star list file (stars observed at a 2-minute cadence) and then use it to build a TESS CTL light curve directory with LcGenerator. If you have any questions, please contact the LcTools author at aschmitt@comcast.net.
Part II. Installing a TESS CTL Star List File
1. Using the tables below, find the star list file you wish to access. Note that there is one table for high numbered star IDs (those with 6 or more digits) and one table for low numbered star IDs (those with 3-5 digits). High numbered star IDs can be used with any LcTools version. Low numbered star IDs can only be used with LcTools version 19.0 and above. Using a version below 19.0 on low numbered star IDs will cause runtime errors.
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.
Primary TESS CTL Star List Files (High Numbered Star IDs -- 6+ digits)
Supplementary TESS CTL Star List Files (Low Numbered Star IDs -- 3-5 digits)
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. Click on the downloaded file to open it in Notepad. You will save the file later on in the process.
Part III. Using LcGenerator to Build a TESS CTL Light Curve Directory
1. Start LcGenerator.
2. In the "Lightcurve Directory" field, type-in pathname "<drive>:\Lightcurves_TESS_S<xxx>" where <drive> is replaced with a target drive letter and <xxx> is replaced with a 3-digit 0 padded sector number. For example, "C:\Lightcurves_TESS_S001".
3. In the Project field, select TESS from the drop-down list.
4. In Notepad, select "File->Save As". Navigate to directory "<drive>:\Lightcurves_TESS_S<xxx>\Generator" and save the file under the same file name. Then close Notepad.
5. Under the "Star List File" field in LcGenerator, click the Select button. In the subsequent dialog box, double-click file "Stars_S<xxx>.txt". The sector number in the star list file must match the sector number in the light curve directory.
6. In the Periods group box, click the Select radio button then type-in the target sector number. The sector number must match the sector number in the light curve directory and star list file excluding the leading "0"s. For example, "1".
7. In the Cadence group box, select 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.
8. Select an applicable flux type (PDCSAP or SAP). PDCSAP is the default.
9. Select an applicable quality filter. The second button is recommended.
10. Click the "Start Job" button to begin building 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.
11. 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.
