Instructions for Reporting your Analysis

Each student will be assigned a collection of light curves (hereafter, "dataset"). These can be found at here. The following assignments have been made: Copy the assigned zip file. After "unzipping" you should find files with names "final_cor_lc_running_lsd_nn.dat" where "nn" is a 1-3 digit number. Hereafter, I will call this as "FILEnnn.dat" For each file: plot the time series and decide whether it is an active galactic nuclei (AGN). If you see slow undulations stretching over a months or years) then it is an AGN. If not then proceed to a periodogram analysis.

Your results file should be called "YourNameResults.txt" file where "YourName" stands for your name.

Please proceed as follows:

  1. Periodgram parameters: P=0.001 to P=1.0 day with step size=1E-5 day
  2. Identify the best period.
  3. Fold the data at the period. Say the best period is Pbest (in days; 6 decimal places).
  4. Enter the following line in your results file "nnn.dat Pbest" (one per line) and if AGN "nnn.dat AGN" and if bad data "nnn.dat BAD"
Repeat above process for the remaining files assigned to you.

PLEASE SUBMIT YOUR WORK PRIOR TO THE END OF THIS WEEK (March 11, 2016).

During the finals week, Thomas Kupfer and I will work compose a short report and then collate your results and write up a paper. All of you will get a draft copy for comments. After we are all satisfied we will submit the paper to Open European Journal on Variable Stars
