Peranso offers a complete set of powerful light curve and period analysis functions to work with large, multi-night astronomical data sets, collected by a variety of observers.  It is equally performant for the individual observer, who is interested in analysing his observations of one or more nights.

Substantial attention has been given to ease-of-use and data accuracy, making Peranso the most productive period or time series analysis software on the market. Peranso lets you take control of your data analysis. Forget intimidating manuals and complex commands - powerful light curve and period analysis capabilities are now within your reach.

Windows 10 support
Peranso 2.60 features full Windows 10 compatibi-lity.
Peranso 2.11 features the Planetary Transit AoV method, a brand new and very efficient method to search for planetary transits in stellar light curves, invented by A. Schwarzenberg-Czerny.
       Transit AoV
   Phase Binned AoV
Peranso 2.10 features the Phase Binned AoV (Analysis of Variance) period analysis method, designed by A. Schwar-zenberg-Czerny.
This method is com-monly used by professio-nal astronomers on a wide variety of variable stars.
Peranso 2.0 boosts many new product features and greatly enhances existing functions. Asteroid light curve work got a strong focus, through (1) the addition of Dr. Alan Harris' [JPL] famous Fourier Analysis method, (2) the ability to plot and use magnitude error bars in period analysis routines, (3) the ability to set the base time for period calculations in hours (instead of days, which is more common for variable star research).

For an excellent introduction to time-series analysis, we refer to the book "Analyzing Light Curves, a practical guide" by Grant Foster (
Peranso 2.60 features full Windows 10 compatibi-lity.
  Exoplanet transits
Peranso 1.33 features the EEBLS method (Kovacs, 2002). This is a box-fitting algorithm  to search for exoplanet transits in survey data.
Although Peranso has been developed as a Microsoft Windows product, several end users are running Peranso successfully on other operating systems too, using appropriate Windows emulation software (also called desktop virtualization software) :
On Apple MacBook computers, we advise to use Parallels Desktop For Mac or the WINE emulator (free of charge), which delivers very good performance in combination with Peranso.
On Linux systems, we advise VMWare Player (free of charge) or the WINE emulator (free of charge), which has been reported to run Peranso flawlessly on Ubuntu.
