Embedded Files
Part I. Introduction
This document describes how to install a star list file for a Kepler time series quarter and then use it to build a Kepler light curve directory with LcGenerator. If you have any questions, please contact the LcTools author at aschmitt@comcast.net.
Part II. Installing a Kepler Star List File
1. If star list directory "<drive>:\Stars_Kepler" does not exist, create it. Any target drive can be used. For example, "C:\Stars_Kepler".
2. Using the table below, find the star list ZIP file you wish to access.
3. Right-click on the file link and select “Open link in new window” from the pop-up menu. Move the window so you can still see these instructions.
Kepler Star List ZIP Files
4. 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:
5. Once your Web browser has downloaded the ZIP file, click on the file to open it. Then extract (unzip) all the star list files into directory "<drive>:\Stars_Kepler". Note that each star list file in the directory contains up to 25,000 star IDs for a part of a time series quarter. Files have the name "Stars_Q<xx>_P<y>.txt" where <xx> is the 2-digit quarter number and <y> is the 1-digit part number within the quarter.
Part III. Using LcGenerator to Build a Kepler Light Curve Directory
1. Start LcGenerator.
2. In the "Lightcurve Directory" field, type in pathname "<drive>:\Lightcurves_Kepler_Q<xx>_P<y>" where <drive> is replaced with a target drive letter, <xx> is replaced with a 2-digit 0 padded quarter number and <y> is replaced with a 1-digit part number within the quarter. For example, "C:\Lightcurves_Kepler_Q05_P2".
3. In the Project field, select Kepler from the drop-down list.
4. Under the "Star List File" field, click the Select button. In the subsequent dialog box, navigate to directory "<drive>:\Stars_Kepler" then select star list file "Stars_Q<xx>_P<y>.txt". The quarter and part numbers in the star list file must match the quarter and part numbers in the light curve directory. For example, "Stars_Q05_P2.txt".
5. In the Periods group box, click the Select radio button then type in the target time series quarter number. The quarter number must match the quarter number in the light curve directory and star list file excluding the leading "0". For example, "5".
6. Select an applicable cadence. 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.
7. Select an applicable flux type. PDCSAP is recommended.
8. Select an applicable quality filter. The first button is recommended.
9. 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.
10. 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.
