Sample TESS target pixel file stack and aperture (TIC 261136679 shown here).

Introduction

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.

Description of Data Products

The target pixel files (TPFs), extracted light curves, and Data Validation (DV) files are stored as FITS or PDF files, with the following naming convention:

• <tid> = TESS Input Catalog (TIC) identifier of the host star
• <s##> = the 2-digit, zero-padded sector number the TPF comes from
• [-##]; = the 2-digit, zero-padded planet candidate number, only present for the dvs.pdf files
• <exten> = "tp.fits" for the target pixel files, "lc.fits" for the extracted light curve files, "dvr.pdf" for the full report PDFs, and "dvs.pdf" for the DV summary PDFs

As an example, here are the full file names for the data products from TIC 52368076, from Sector 1, for the second planet candidate:

hlsp_tess-data-alerts_tess_phot_00052368076-s01_tess_v1_dvr.pdf
hlsp_tess-data-alerts_tess_phot_00052368076-s01_tess_v1_lc.fits
hlsp_tess-data-alerts_tess_phot_00052368076-s01_tess_v1_tp.fits

Some targets have additional data validation reports that include information from multiple sectors. In those cases, the files include multiple sector numbers in the dvr.pdf and dvs.pdf files. For example, the "dvs.pdf" files and the "dvr.pdf" file for the target TIC 51912829 that has three planet candidates and include data from both sectors 1 and 2 are named:

hlsp_tess-data-alerts_tess_phot_00051912829-s01s02-01_tess_v1_dvs.pdf
hlsp_tess-data-alerts_tess_phot_00051912829-s01s02-02_tess_v1_dvs.pdf
hlsp_tess-data-alerts_tess_phot_00051912829-s01s02-03_tess_v1_dvs.pdf
hlsp_tess-data-alerts_tess_phot_00051912829-s01s02_tess_v1_dvr.pdf

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.

Data Access

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. Rows containing data products that analyze multiple sectors of data together are denoted by multi-sector strings, e.g., "1-3" for data that span Sectors 1 through 3. But note: the range is the possible minimum and maximum Sectors used, it does not mean data was necessarily used from each Sector in the range in that column or file name. Always consult the information contained with the data validation reports to determine what data was used to generate those reports. Some planet candidates only have sector-combined data validation files, in those situations, the individual sector DV table cells will be empty, and the corresponding sector-combined DV files should be the primary reference for data validation information.

Note: Some TOI's were identified from the Full Frame Images using an MIT "Quick Look Pipeline" (QLP). These do not have 2-minute cadence products at the time they were announced, and are identifed as such with "FFI" and "FFI-QLP" in the table below. Download the Full Frame Images from the mission data products for these targets using MAST interfaces like TESSCut, the Portal, Astroquery, or bulk downloads.
