Processing of data from the instrumentation system of the SPIRIT telescope-spectroheliograph

Abstract

The scientific purpose of the SPIRIT experiment is to study the space-time structures of phenomena of the solar activity using a set of X-ray instruments aboard the Koronas-F satellite. The system consists of the SRT-C six-channel telescope and the RES-C four-channel spectroheliometer for 8.4- to 335-Å wavelengths and the SPR-N five-range polarimeter for 20- to 100-keV energies. For a 3.5-yr flight (since July, 2001 to January, 2005), over 40000 observation sessions were conducted and over 1 million spectral pictures were obtained during the SPIRIT experiment. The volume of electronic archive of the experiment reached 220 Gbyte. The software package was developed for prompt control of the scientific system and used in the semiautomatic mode to form the sequence diagrams of energizing, create control files (CFs) via the dialog line, and schedule CF delivery. The software package is based both on the electronic table in the Excel-2000 format, which displays the basic procedures and control events, and on the database in the Access-2000 format, which is automatically filled with the information on all created CFs. For archiving, viewing, and selecting scientific data of the experiment, a graphic database in the Access-2000 format was created. The software for automatic filling of the database and a graphic interface for prompt viewing of the database and retrieval of pictures based on some parameters were designed. An automatic augmentable ballistic database containing basic parameters of the satellite orbit over the full flight period was created.
