... The planning and reduction programs are distributed with array sizes set large enough to let most observers work without difficulty. However, you might need to reduce a very large data set, or to deal with a very large number of passbands (9 is the nominal limit). ...

Data in GIPSY is stored in so called sets . A set consists of two components: an image component and a descriptor component. These components are stored in separate files, but in GIPSY they are always used together. The image data is stored in a `crystalline' structure with a virtually unlimited (up to 20) number of dimensions. ... Within a set subsets can be defined. ... The figure below shows the possible subset types in a three-dimensional set, a `` cube '': . ...

... Properties of Dust Grains in Planetary Nebulae - I. The Ionized Region of NGC 6445 . ... Based on this model, we show from depletions in the gas phase elements that little grain destruction can have occurred in the ionized region of NGC 6445. ... The most likely conclusion is that grains are residing inside the ionized region of NGC 6445 and that the low temperature and flux of the grain emission are caused by the low luminosity of the central star and the low optical depth of the grains. ...

As a result, a common magnitude scale (contour lines on the maps above, or color scale on Fig.1) will poorly display the short-duration events in a signal. Normalizing each line of the map (fixed duration) so it has unit variance (in effect dividing the energy map by the mean energy spectrum) at each duration restores more details of small-scale activity (Fig. ...
