Working sets, SDRECORDs, and everything else

Results are either working sets (also known as sditerators), SDRECORD, and anything else.

A working set is a collection of SDRECORDs. Specifically, it is an sditerator tool. When you open a data set through the File menu (either a new one or an existing one) the result is a working set which will be shown in the results manager. The other way to create a working set is to use the ``Apply'' button in the ``Selection'' operation. When you make a selection this way the result is also a working set. It does not make a copy of the selected data, rather it makes a reference to the selected data in the underlying data. This means that if you change the underlying data, the reference in the selected data is also changed. Working sets can be browsed. See the Reference Manual for more information on the Sditerator tool.

An SDRECORD is a Glish record which has the structure described in Appendix A. It is data (generally spectra at this point in DISH development) plus some standard header values, any non-standard header values, and a history of what has been done to that particular SDRECORD. SDRECORDs can be browsed and plotted.

Anything may appear in the results manager. If it isn't a working set or an SDRECORD it can not be browsed or plotted.
