The pipeline results will be automatically stored in a database. By using the same software in an interactive way parameters can be adjusted to optimize the analysis. This amounts to a needed storage capacity of roughly 250 Mbyte per day or 90 Gbyte per year. Together with analysis results an average of 120 Gbyte of data must be stored each year. Additional requirements are to provide parameters to check and plot the WFCs state of health and functioning and to plot the satellite attitude and ephemeris.
File formats follow the FITS standard.
This should allow for a reasonably portable system. Configuration control is achieved through a combination of the Revision Control System and an Oracle database. Access to NeSDaC will be possible via telnet and the X Window system. For public data, software downloading and retrieval of results, an anonymous ftp and WWW server can be used. Via WWW forms data can be located and collected, in addition invoking analysis runs will be possible.
