Methods of Data Analysis on TESS Observations

We present follow-up observations of TESS targets conducted by our research group at George Mason University. Targets were observed nightly through a 0.8m telescope, and chosen through the SG1 TESS Transit Finder. Using AstroImageJ, a software package for image processing, our team reduced, platesolved and performed aperture photometry on images of targets. Apertures were chosen through accounting for seeing, nearby companions, and target brightness. Comparison stars were then reviewed, and target light curves were detrended using various observation parameters. AstroImageJ was used to run a NEB star check, and transits of the target were modeled through ExoFASTv2. Findings from this data analysis have contributed to multiple TOI detections and continue to expand the validation of candidates from the TESS mission.
