1st Mar 2019: Fourth release of TESS Data for Asteroseismology

We are pleased to announce the fourth release of TESS data for asteroseismology from the TASC Coordinated Activity T'DA.

For this release raw photometry is provided based on Full Frame Image (FFI; 30-min) and Target Pixel File (TPF; 2-min) data from TESS Sectors 1+2. All data is accessible via the "Data Search" interface. In total 1,733,576 light curves are provided with this release.

Please note that no corrections have been applied to the light curves. We are working hard on the implementation of the co-trending component of the T'DA pipeline, but release raw photometry now to allow the community to have a first look at the full data sets.

Please read the full data release notes for more details. To optimize the photometry pipeline we are very interested in knowing of any issues or shortcomings you find. Therefore, if you have any comments or questions regarding the processed data, please let us know.

You will be able to download all data from sectors 1 and 2, both from the SPOC and TASOC. And you will be able to get all lightcurves in ASCII format as well.
