This page assists with the usage of the Template Fourier Fitting code originally implemented for deriving the Fourier decomposition of period-folded RR Lyrae light curves with gaps (see Kovacs & Kupi 2007 ). The menthod can be used for the same purpose on any other types of variables, assuming that the the template database is changed to the proper type of variables.

Comments:

• Although the code has been tested thoroughly, bugs may still be hidden.
  
• The code is not necessarily optimally written.
  
• In the ideal case the code should be supplied by a graphical package for data visualization.
  
• Possible bug reports can be sent to kovacs[at]konkoly.hu
