7.1.1 SSWHERE

SSWHERE is a widget-driven program that creates an array of subscripts (ss) that fulfill a set of criteria that you define to select SXT images. For example to make an ss array for YODAT where you want to select images from a data set represented by roadmap, you merely type:
IDL> ss=sswhere(roadmap)
  SSWHERE works on both the roadmap and index structures. Available selection criteria are:

• completeness of the image
• SXT mode (normal/dark image/calibration)
• pixel resolution
• compression mode
• filters
• exposure DPE
• DP mode
• field of view location (see lower buttons)
• time period (see lower buttons)

If you get a ``No matching Data'' response, check that you have selected all possible options.
