Abstract

This paper is an addendum to the paper, “CCD Photometry, Period Analysis, Light Curve Deconvolution, and Evolutionary Status of the High Amplitude δ Scuti Variable Star GSC 4606-1045 (Vend 33)” (Gilchrist, JAAVSO, 53, 24 (2025)). The referee for that paper had challenged the author to include data from the Transiting Exoplanet Survey Satellite (TESS) in the analysis for GSC 4606-1045. After the original paper was accepted on January 9, 2025, TESS data from sectors 58, 59, 78, 79, 85, and 86 became available. That data provided new times of maxima (ToMx) for predicted time difference (PTD) analysis, and additional data for discrete Fourier transforms (DFT). Combined with data from the original paper, the TESS data provided an updated linear ephemeris and improved DFT results.
