Objects

The ASAP interface is based around a number of ``objects'' which the user deals with. Objects range from the data which have been read from disk, to tools used for fitting functions to the data. The following main objects are used :

scantable The data container (actual spectra and header information)
selector Allows the user to select a subsection of the data, such as a specified or range of beam numbers, IFs, etc.
plotter A tool used to plot the spectral line data
fitter A tool used to fit functions to the spectral data
reader A tool which can be used to read data from disks into a scantable object (advanced use).

There can be many objects of the same type. Each object is referred to by a variable name made by the user. The name of this variable is not important and can be set to whatever the user prefers (i.e. ``s'' and ``ParkesHOH-20052002'' are equivalent). However, having a simple and consistent naming convention will help you a lot.
