Two STSDAS tasks are available that will display only certain sections of the help file.
STSDAS Package Structure
STSDAS version 1.3 is structured so that tasks are logically grouped. In many cases, you can easily find a task that does whatever function you need simply by looking in the appropriate package. For example, all of the tasks that are used in the calibration process can be found in the hst_calib package and tasks used for general image display and plotting can be found in the graphics package. Figure 2.7 shows the STSDAS package structure.
Sample data sets are also provided with STSDAS so that you can experiment with tasks for which you might not otherwise have suitable data. The sample data sets are found in the directory scidata$.
High-level descriptions of nearly every STSDAS package are available within the IRAF online help facility using the opt=sys qualifier. For example, to see an overview of the packages and tasks in the hst_calib package you could type: help hst_calib opt=sys
If you have problems using STSDAS or IRAF and you can't find the solution in the manuals or the on-line help, you can contact the STSDAS user support staff by sending e-mail to: email@example.com
