TL;DR

This paper presents the delivery of RMS CDPP tables for TESS 2-minute cadence targets, providing a valuable resource for assessing photometric precision and signal-to-noise ratios across multiple sectors.

Contribution

It provides a comprehensive set of RMS CDPP values for all TESS 2-min targets across sectors 1-90, enhancing data accessibility for transit detection analysis.

Findings

01

RMS CDPP values cover 15 trial transit durations from 0.5 to 15 hours.

02

Tables enable estimation of signal-to-noise ratios for transiting exoplanet detection.

03

Continuous delivery of RMS CDPP tables supports ongoing TESS data analysis.

Abstract

We report the delivery to the Mikulski Archive for Space Telescopes (MAST) of tables containing Root Mean Square (RMS) Combined Differential Photometric Precision (CDPP) values for all TESS 2-min cadence targets with Science Processing Operations Center (SPOC) light curves in Sectors 1-90. Each comma-separated values (CSV) file contains CDPP values for all 2-min light curves in the given sector. The tables include robust RMS CDPP values for the 15 trial transit pulse durations searched in the SPOC 2-min processing pipeline, ranging from 0.5-15.0 hr. For each pulse duration, CDPP is computed in the transit search for a trial transit centered on every cadence. The RMS value of the CDPP time series is a metric that may be employed to estimate signal-to-noise ratio for transits with the given duration and a specified depth. We will continue to deliver the RMS CDPP tables to MAST for each…
