Toward Optimal Photometric Calibration of Digital Astronomical Plates with Deep Learning

Photometric calibration of digitized photographic plates is commonly modeled with separable magnitude-, color-, and position-dependent terms, but this separability can break down when image quality varies across the field in a magnitude-dependent way, leaving coupled spatial systematics in the residuals. We introduce a...

High-precision Astrometry of Saturnian Major Satellites: Halo Reduction and Optical Filter Evaluation

High-precision astrometry of planetary satellites is important for refining ephemerides and supporting deep-space exploration missions. We apply the Bilateral-filtered Single-Scale Retinex with Gaussian regularization (BSSR-Gaussian) method to 140 CCD images of Saturn obtained at Yunnan Observatory and evaluate the p...
