Towards optimal photometric calibration of digital astronomical plates with deep learning
Mingyang Ma, Haibo Yuan, Lin Yang +8
Photometric calibration of digitized photographic plates is commonly modeled with separable magnitude-, color-, and position-dependent terms, but this separability can break down w…
The Astronomical Plate Digitization at SHAO
Yong Yu, Meiting Yang, Zhengjun Shang +5
The digitization of historical astronomical plates is essential for preserving century-long observational data. This work presents the development and application of the specialize…
Digitization of Astronomical Photographic Plate of China: Photometric Calibration of Single-exposure Plates and Release of Photometric Catalogs
Ma Mingyang, Yuan Haibo, Xiao Kai +15
The Chinese Plate-Digitizing Project has digitized a total number of about 30,000 astronomical plates from 11 telescopes of five observatories (SHAO, NAOC, PMO, YNAO, and QDO) in C…
Digitization of Astronomical Photographic Plate of China and Astrometric Measurement of Single-exposure Plates
Zheng-Jun Shang, Yong Yu, Liang-Liang Wang +9
From the mid-19th century to the end of the 20th century, photographic plates served as the primary detectors for astronomical observations. Astronomical photographic observations…
