The Official STIS Aperture List for Cycle 17

Table 9.5 lists the apertures in STIS that are Supported for Cycle 17; they are noted with an "Ok." This table has been carefully checked for completeness and accuracy, and should be taken as the final word for Cycle 17.

Revisions to documents occur as needed to keep them up-to-date. If a discrepancy is found in this or other documents (such as the Data Handbook or STIS Instrument Handbook), the table here should be considered definitive and correct.
