We are pleased to announce the sixth release of TESS data for asteroseismology from the TASC Coordinated Activity T'DA.
For this release, raw and systematics corrected photometry is provided based on Full Frame Image (FFI; 30-min) and Target Pixel File (TPF; 2-min) data from TESS Sectors 14+15+26. These TESS Sectors overlaps with the original Kepler field of view, and therefore provide unique oppotunities for asteroseismology of previously known favorite targets.
All data is accessible via the TASOC website. In total a little over 9.7 million light curves are provided with this release.
This release, like the previous ones, provide systematics corrected data using two different methods: Co-trending Basis Vectors (CBVs) and Ensemble photometry. Most observed targets will thus have two light curves, and we encourage you to check both corrections for the optimal light curve for your science. You can read more about the photometric pipeline and the two correction methods, and their individual pros and cons, in the T'DA papers, which can be found here: Photometry, Corrections.

We are pleased to announce the fifth release of TESS data for asteroseismology from the TASC Coordinated Activity T'DA.
For this release, raw and systematics corrected photometry is provided based on Full Frame Image (FFI; 30-min) and Target Pixel File (TPF; 2-min) data from TESS Sectors 1-6. All data is accessible via the TASOC website. In total a little over 12 million light curves are provided with this release.
For the first time, this release provides systematics corrected data using two different methods: Co-trending Basis Vectors (CBVs) and Ensemble photometry. Most observed targets will thus have two light curves, and we encourage you to check both corrections for the optimal light curve for your science. You can read more about the photometric pipeline and the two correction methods, and their individual pros and cons, in the T'DA papers, which can be found here: Photometry, Corrections.

To optimize the TASOC 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.
Our strategy for the next TASOC data release is to focus on the TESS Sectors overlapping with the Kepler field of view. After that we are aiming for a more rapid release schedule where the following sectors will be released one after the other.
As you may have read in the news from the TESS Science Support Center, the TESS data from sectors 1-19 are going to be reprocessed and updated in the coming months. This will mean that as data is re-released, they will no longer be available on the MAST archive.
But fear not! On the TASOC archive, we will make sure that all previous versions of data will always be available, so you can always reproduce your TESS results.
