WebApr 4, 2024 · The wide-field telescope is a research hotspot in the field of aerospace. Increasing the field of view of the telescope can expand the observation range and enhance the observation ability. However, a wide field will cause some spatially variant optical aberrations, which makes it difficult to obtain stellar information accurately from … WebHawaii Telescope (CFHT) and Hubble Space Telescope (HST) observations, supplemented with Chandra data to determine the precise astrometry. The details of the five X-ray sources can be found in Table 1. This paper is organized as follows. In Section 2 we present the optical and X-ray observations and data re-duction.
