Design and Implementation of Random Sampling System of Astronomical Spectrum
Yue Lili, Wang Guangpei, Pan Jingchang · 2018
Spectral library contains massive celestial spectra, including millions of spectral data of various types, and the spectral information is mainly stored in FITS file. In astronomical research, it is often necessary to obtain various spectra quickly and easily. We designed and implemented a system was designed to achieve this goal. There are four parts of the system: FITS file read, SDSS information access, User interface and FITS file access. The System is an implementation for the local storage of FITS files, and it is convenient and quick to obtain sampling spectra randomly on demand. In this paper, the key techniques, the design and implementation in the system are introduced in detail. The system runs stably and efficiently after a period of practical application, and achieves the goal of fast file positioning. It provides a convenient platform for astronomical researchers.
