J/AJ/127/1360       Star-forming knots in NGC 4194 center    (Weistrop+, 2004)

Looking closely at medusa: star-forming knots at the center of NGC 4194. Weistrop D., Eggers D., Hancock M., Nelson C.H., Bachilla R., Kaiser M.E. <Astron. J., 127, 1360-1370 (2004)> =2004AJ....127.1360W

A complete sample of 38 UV-bright knots is identified. Description: The CCD integration was divided into two 150s integrations to ensure identification and removal of cosmic-ray events. All data were obtained on 1998 October 13 UT.

Note (1): The detector scale is 0.0246"/pix for both MAMA detectors and 0.0507"/pix for the CCD detector. Note that the field of view of the CCD image is larger than that of the ultraviolet images. The image centers have J2000 coordinates RA=12 14 0.96, DE=+54 31 29.2 (Fig. 2, STIS FUV image of the center of NGC 4194) and RA=12 14 0.96, DE=+54 31 29.1 (Fig. 3, STIS CCD image of the center of NGC 4194) North is up, and east is to the left. Note (2): In units of erg/s/cm2/Å. See "Table 1" section above for details
