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 can now search for TESS data through the TASOC website as easily as you have been able to search in the TIC. Just click the "Data Search" tab at the top of the page.
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.
We have added some small code-snippets on how to load in FITS files in various languages (Python, IDL, Matlab) under "Documentation and Help".
In the future, the plan is that the TASOC website will also provide ASCII versions of light curves, as an alternative to the FITS files. These do use more disk-space than their FITS counterparts and will contain less information, so we would recommend to use FITS if possible.
