In this chapter we describe the imaging capabilities of STIS. Each imaging mode is described and plots of throughput and comparisons to the capabilities of WFPC2 and ACS are provided. (Signal-to-noise comparisons to WFPC2 assume the use of the WF chips.) Curves of sensitivity and exposure time as a function of source brightness to achieve a given signal-to-noise ratio are referenced in this chapter, but presented in Chapter 14. We note the existence of bright-object observing limits for MAMA imaging modes which are described in detail in Chapter 7, and tables of the MAMA imaging bright-object screening magnitudes as a function of mode and spectral type which are presented in Chapter 14.
