Next: Using a Java Web-based Graphical User Interface to access the SOHO Data Archive . ... A major problem with designing archives in astronomy is defining the data resolution. ... Expert users can create User Defined Functions (UDFs) that extract virtual attributes from files external to the database engine. ... Therefore, for the ISO Post Mission Archive, the concept of virtual data resolution with user defined functions has been designed and implemented as a novel database paradigm. ...

... All the parameters provided in this database have been obtained using the the MIRIAD ( Sault et al. 1995 ) task MBSPECT . MBSPECT makes a spectrum of the velocity (or frequency) axis of a cube. The spectrum is beam-weighted, over the width specified, for the other image axes. ... Robust parameters are calculated by using an algorithm which minimises the mean absolute deviation of the flux-weighted velocities. mask= This specifies the x-axis ranges to be excluded from any continuum fit. ...

... The perceptron structure, on the basis of which the database is built, is defined by a number of the input and output parameters and a required accuracy. ... The output perceptron data are the expansion coefficients of the scattering matrix elements in series of the generalized spherical functions. ... As the cluster structure depends on the generation conditions the expansion coefficients were averaged over 5--7 realizations of the clusters (for N . ... is the coefficient number. ...
