The Design And Implementation Of LAMOST Working And Research Collaboration Platform

In astronomical research, astronomical researchers often work in different places due to their disciplines and the distribution of the observation equipments. Yet, collaborations among different departments in different working places are required in the astronomical data processing and researching work. During the process of LAMOST Sky Survey, huge amount of spectral data is generated, which makes it particularly important to process the spectral data of daily observations centrally and extract valuable spectra effectively.For special astronomical spectra, intuitive one-dimensional spectral images can show the spectral features effectively, helping researchers to identify special and rare celestial bodies more easily. In addition, the researchers need immediate and effective exchange of discussion and information feedback during the discovery of special and rare celestial bodies, and the original viewpoints proposed in the discussions need to be classified, extracted and archived for future inquiries.Since the observation band of various telescopes is different, the multiband accreditation of the same celestial is an effective method for testing the spectral quality. Through the cross authentication of the same celestial’s observational data, the special spectral lines and the data errors occurred during the observation process can be distinguished effectively.This work is mainly divided into three parts:(1) Constructing the LAMOST Working and Research Collaboration Platform. This is to achieve the function of the instant message pushing of multi-client in different places so that the staff in different places can communicate and collaborate online instantly, and related researchers can discuss and analyze together on the spectral data and spectral images. This module uses the HTML5WebSocket protocol, which making it possible for the client communicate instantly like desktop systems in he C/S architecture, and having significant pertormance advantages in the stabuny und the amount of data transmission compared with the traditional polling techniques(2) Implementing the functions of uploading and automatically parsing the local (?)pectral file and plotting a one-dimensional vector graphics. Moreover, multi-clients can obtain real-time information of the spectral image, which is displayed and apdated simultaneously. The operations of scaling, marking spectral features and erasing the handwritings are allowed. This module adopts AJAX to achieve the unction of asynchronous uploading and parsing of the spectral filc and returning the spectral data, and uses HTML5Canvas technology to draw a one-dimensional vector spectral graphics and user mark handwriting based on the Ext JS framework.(3) Realizing the functions of uploading and parsing the spectral file and reading he right ascension and declination parameters. The user can specify the error range so hat the system invokes the WebService to conduct multi-band cross-certification, and (?)ccreditation data is plotted together with the spectral image. In order to realize the spectral quality inspection, the user can manipulate the accreditation data to calibrate flow deviation.
