Image Details
Caption: Fig. 2.
STIS FUV‐MAMA (left panels) and STIS optical‐band CCD (right panels) images. The far‐UV frames have been smoothed by a Gaussian with ﹩\mathrm{FWHM}\,=0\farcs 24﹩ (10 pixels) in order to improve the contrast of the resolved sources against the background. The CCD frames, which have larger fields of view, were cropped and scaled to match the ﹩25^{\prime \prime }\times 25^{\prime \prime }﹩ FUV‐MAMA frames. The resolved objects in the optical frames are all GCs. Most UV‐only sources in the far‐UV frames are probably background UV‐bright galaxies (see § 9). The top row shows field 1; the middle row shows field 2 with a background galaxy at right center. The bottom row shows field 3. Because of the strong background gradient in this field, we subtracted a median‐filtered image from both panels. The irregular shading in the FUV‐MAMA image is a result of co‐adding images with two different position angles.
