The TESS mission has organized a working group to investigate “sector stitching” effects, and invites interested community members to participate.
"Sector stitching" refers to a common challenge in TESS data where a source’s measured flux is observed to be discontinuous across sector boundaries. The TESS mission is currently investigating calibration techniques to seamlessly "stitch" this data together into single, extended light curves. Creating these longer baselines is essential for advancing numerous scientific studies, such as tracking long-period variable stars, observing long-term trends, and detecting slowly evolving extragalactic transients.
The group comprises of a diverse array of participants, including personnel from the TESS project and representatives from the broader scientific community. If you are interested in participating, please contact Michael Fausnaugh (michael.fausnaugh@ttu.edu), and you will be added to a distribution list for upcoming meetings. We expect the group to meet approximately monthly, with subgroups investigating different effects and calibration methods.
