Digitized Data of China Astronomical Plates: Image and Astrometric Catalog
Publish Time:2024-03-08
Astronomical plates are the precious heritage of astronomical observation research. With the support of the Special Key Project for Fundamental Work in Science and Technology of the Ministry of Science and Technology, the Shanghai plate digitization laboratory completed the scanning and archiving of 29,314 plates in 2017. On this basis, the research team of Shanghai Astronomical Observatory conducted further astrometric calibration work on the digitized astronomical plates based on the Gaia DR2 catalog, converting the initial version of the digital plates into astronomical digital images in the standard fits format to satisfy the research work of relevant professional astronomers. The current data release contains 15,696 high quality digital plates and corresponding astrometric results, with the observation targets mainly being extrasolar objects. This batch of data contains observations from nine telescopes at five Chinese astronomical stations, namely, the National Astronomical Observatory, the Shanghai Astronomical Observatory, the Purple Mountain Observatory, the Yunnan Astronomical Observatory, and the Qingdao Observatory, and spans the period from 1901 to 1998. The astrometric precision is mainly related to the focal length of the telescopes. For the plates of long focal length telescopes, such as the 40cm binoculars refractor telescope and the 1.56-meter reflector telescope of the Shanghai Astronomical Observatory, and the 1-meter reflector telescope of the Yunnan Astronomical Observatory, the astrometric precison can be as high as 0.1-0.3″. The differences between this release and the "Digitized Data of China Astronomical Plates: Early Data Release" are as follows: (1) The fits header information of all 6,615 astronomical plates in the early batch has been updated, and the astrometric results of these plates have been added. (2) 9081 astronomical plates and the corresponding astrometric results have been added.
