Monthly Progress Report


Period: 2000-04-01--04-30

Authors: Lars Eliasson and Peter Wintoft

1. Progress status

During April the following documents on the SAAPS server have been updated:

1. SRD version 0.3, 2000-04-03

2. TN2 version 0.2, 2000-04-03

3. URD version 1.1, 2000-04-27

Items 1 and 2 were also announced in the March report. See: http://www.irfl.lu.se/saaps/saapsin t/

On April 18 the FTP server at SEC was upgraded which lead to very slow performance of the Java programs that connected to it. Unfortunately, we upgraded the Java virtual machine (JVM) on the SAAPS server almost at the same time. As we did not know about the SEC upgrade at that time we spent a couple of days trying to understand what the problem was as we believed that it was the JVM update that caused the problems. However, after contact with SEC we understood the cause of the problem and they have now configured their FTP server so that it works for the Java programs.

On the SAAPS models page there is now an applet to perform superposed epoch analysis. The program lists the available SAAPS data and the user can select a parameter to study. The user must also specify the event window size, which can be in days, hours or minutes. The user must also provide an event list, which is directly typed in or copied and pasted from some text file. Then a plot with the data is presented. The future version will include the possibility to cancel a data download, help pages, and downloading of averaged data. See: http://sol.irfl.lu.se/s aaps/saapsint/saapsmodels/

OMNI database classes have been created. The OMNI data for the years 1982 to 1999 have been added to the SAAPS database. The program that builds the OMNI database on SAAPS connects to the OMNI FTP server and automatically downloads the data. The original data starts in 1963 and the SAAPS database can easily be upgraded to also include these data.

On April 17 the SAAPS letter with the questionnaire were sent to the following people:

Palle Soerensen, Address Code TOS-OGE, Company Name ESA, Telephone (10491) 2793, Internet Address psoerens@esoc.esa.de

Paolo Maldari, Address Code TOS-OGI, Telephone (10491) 2477, Internet Address pmaldari@esoc.esa.de

Howard Nye, Address Code TOS-OGX, Telephone (10491) 2719, Internet Address hnye@esoc.esa.de

Mike McKay, Address Code TOS-OGM, Telephone (10491) 2629, Internet Address mmckay@esoc.esa.de

Paolo Maldari and Howard Nye answered very quickly. Howard Nye will pass the questions to the Head of the Flight Operations Division. Paolo Maldari gave an extensive answer to the questions.
