This page is intended to provide a collection of combined gamma-ray lightcurves of variable objects from different experiments. For the first time in gamma-ray astronomy, we provide combined long-term lightcurves from different experiments in a unified standard data format. As more and more data become published, this data repository will grow.

Since no standard data format was used by most experiments in the past (and still is), we collected data in many different formats and converted them to the standard FITS format. Furthermore, no common definition of what data fields a lightcurve file should contain existed up to now. Therefore, we have developed the simple lightcurve format (SLF) definition, which defines the data fields needed for subsequent analyzes of lightcurve data. The SLF data field structure is defined here. For the contents definition of the data fields of the FITS files we use the SLF definition.

Please report any bugs to us !

Combined lightcurve plots

Combined data files

Here, we provide combined lightcurve files in FITS format. The data fields in the fits files comply to the SLF definition. The file versions are given by their creation date. When new data will be available, this table will be extended accordingly. Direct contributions of data in electronic form are welcome (send e-mail to us).
