The TESS mission successfully launched on 18 April 2018 and began science operations on 25 July 2018. Observations of science Sector 1 were performed from 25 July to 22 August, during which pixel data from nearly 16,000 objects were collected at two-minute cadence. These data were sent to the Science Processing Operations Center (SPOC) at NASA Ames for calibration, reduction, cotrending, and transit detection. The potential planet signatures, in the form of Threshold Crossing Events (TCEs), were reviewed by the TESS Science Office to identify targets for imaging and spectroscopic follow-up. A total of 44 high-quality planet candidates in Sector 1 were initially selected from the two-minute cadence data for follow-up observations by the TESS Follow-Up Program (TFOP). In the table below, the target pixel files, extracted light curves, and data validation reports for planet candidates identified as TESS Data Alerts are made available for download.
The release notes describing these products can be downloaded via the Data Release Notes link at the top of this page. You can refer to the full collection of TESS-DATA-ALERTS data products using the DOI http://dx.doi.org/10.17909/t9-wx1n-aw08.
In addition to the TPF and DV files, a .csv table containing information on the TOI's released as part of the TESS data alerts HLSP is also included in the table below. The .csv columns are:
TIC ID, TOI ID, Disposition, RA (deg.), Dec. (deg.), TESS mag, TESS mag uncertainty, Primary Transit Epoch (T0) (BJD - 2457000.), T0 Uncertainty, Orbital Period (days), Orbital Period Uncertainty, Primary Transit Duration (hours), Primary Transit Duration Uncertainty
Note that the names of files released as part of the Data Alerts HLSP do not follow the same naming convention as TESS data products in the full public release. Except where and if noted, the Data Alerts files are produced by the TESS mission pipeline. The format and structure of those products are identical to the ones to be released in the first TESS data release.
The data products are available for download through the table below. A bundle of all data products for all targets is available for download at the top of the table. Note that the exoplanet parameters are from the Sector 1 information when an exoplanet candidate is present in both Sector 1 and Sector 2.
