Time Series and Light Curves

This page is for posting materials and links relevant to the exchange of light curve data.


The following documents develop the VO time series standards:

Use Cases

With the increasing importance of synoptic surveys in modern astronomy, the IVOA could expand its repertoire of data objects to include time series data (Light Curves). An interoperable protocol for exchanging light curves would open the current tight connection between data and classifiers. I propose that the IVOA work towards a Simple Light Curve Access Protocol (SLiCAP) for the following science reasons:
  • Data from survey A can be analyzed by software from group B
  • Data from survey A can be compared and fused with data from project B
  • An internationally standard format for representing light curves
