Design and Implementation of Automatic Astronomical Spectra Data Processing System

Abstract

Astronomical observation produces a large amount of data. The effective storage of the data is an important work. In this paper, the automatic processing of this kind of data was studied in order to solve this problem. The log file, the personnel on duty manual record data and information in exposure are integrated to display and process in a single interface. It makes the sky region information storage and spectrum information storage simple. Based on actual demand we designed the automatic storage system. Instead of manually putting the log into storage, users now can modify the contents of the automatic storage information by checking logged data to ensure correct information. Actual practice indicates that this system improves the efficiency of data processing greatly. Introduction Astronomical observation produces a large amount of data every day. We must organize these data together and save them in databases in order to process and publish them for further use. We study the method of log storage in this paper. The log information consists of two parts, one is the sky information and the other one is the spectrometer information. The whole sky is divided into many regions in order to be identified easily, each region simply being called a sky. The information of a sky contains the identified number, phase of the moon, exposure time, seeing, center RA, center Dec, etc. These information needs staff in NAOC (National Astronomical Observatories, Chinese Academy of Sciences ) integrates the log file and the exposure data, then inserts them into databases one by one. Observation data is always very large and the processing is difficult. Also manual operation is inefficient and error-prone. In this paper we make the operation easier and more accurate by automatic process of the observation data. We design the automatic log storage system in order to put the data into databases based on the exposure data and log file automatically instead of tedious manual operation. The system based on java + hibernate + bootstrap + jquery technology in B/S[1][2] architecture, a good solution to solve the portability problems. Module Design The log storage system consists of three parts: logged, unlogged, and auto-storage. The module “unlogged” displays the list of dates in which the log has not been put into databases. The module “logged” shows the dates in which the logs have been saved. The logs have been put into the database already and those have not been saved are all divided into groups by year in reverse order. The third part “auto-storage” can save the observed information automatically in a date range. The system modules chart is shown as Fig.1.
