Erratum: “Improved Orbital Constraints and Hα Photometric Monitoring of the Directly Imaged Protoplanet Analog HD142527B” (2022, AJ, 164, 1)

This erratum corrects two errors in the published article (Balmer et al. 2022). First, we implement two corrections to our published photometry. We improved our data reduction pipeline for photometric extraction and calculation of the Hα luminosity of the companion, both of which now follow the procedure described in detail in Follette et al. (2023). The updated photometric calibration and BKA model fitting results in astrometry that is identical to that reported in Balmer et al. (2022) to within uncertainties, so we do not repeat the orbital analysis here. We do, however make a small correction that arose from a numerical error in the calculation of the mutual inclination angle between the binary orbit and the inner and outer disk planes. Neither correction results in a change to the main conclusion of the paper, namely the orbital solution for HD 142527 B. The evidence for a near perpendicular orientation for the binary relative to both disk planes remains strong. The updated photometry, which manifests primarily in an increase in photometric uncertainty does, however, cast into doubt the tentative claim made in the original article of photometric (and therefore accretion rate) variability in the excess Hα emission of HD 142527 B.
