CHAPTER 1. INTRODUCTION 53 Figure 1.1: Screen shot of the default CASA inputs for task clean. Text Font Parameters: plain bold plain Values: plain plain plain Text Color Highlight Indentation Meaning black black green none grey none none none yes standard parameter expandable parameter sub-parameter black blue red none none none none none none default value non-default value invalid value Figure 1.2 shows what happens when you set some of the clean parameters to non-default values. Some have opened up sub-parameters, which can now be seen and set. Figure 1.3 shows what happens when you set a parameter, in this case vis and mode, to an invalid value. Its value now appears in red. Reasons for invalidation include incorrect type, an invalid menu choice, or a filename that does not exist. For example, since vis expects a filename, it will be invalidated (red) if it is set to a non-string value, or a string that is not the name of a file that can be found. The mode=’happy’ is invalid because its not a supported choice (’mfs’, ’channel’, ’velocity’, or ’frequency’). 1.3.5.5 The saveinputs Command The saveinputs command will save the current values of a given task parameters to a Python (plain ascii) file. It can take up to two arguments, e.g. saveinputs(taskname, outfile)
