We will first load the R Leo observations in a Peranso Observations Window. You have two options for this:


  1. Import the R Leo observations in real-time from the AAVSO International Database

    In the section Importing observations from the AAVSO AID of Tutorial 1, we have learned how to create an Observations Window by importing observations from the AAVSO AID. Repeat these steps for R Leo, knowing that we want to limit the Data range from 2000 till 2010, and that we are interested in visual observations only.

    The Plot Lightcurve from AAVSO database dialog box should look as follows:




  1. Load the R Leo observations from a Peranso project file


In the section Loading observations from a Peranso project of Tutorial 1, we have learned how to create an Observations Window by opening the corresponding Peranso tutorial project file. Repeat these steps for R Leo, this time selecting the tutorial folder 2. Performing a period analysis.



In both cases, your newly created ObsWin should look as follows:



Using the Observations Window Info box (see Tutorial 1) you can cross check that your light curve contains approximately 14.748 observations (the actual number might be slightly different, as the AAVSO AID is being constantly updated).
