Image Details
Caption: Figure 3.
Top row: the central ionizing binary of the Trapezium: θ
1 Ori C as imaged with MagAO's VisAO CCD camera in different filters. Note the excellent resolution in the raw 60 s image.
We note that no post-detection shift and add (SAA) was applied, nor was there any frame selection used to produce these top
row images. Typically we achieved resolutions of 0
026–0
029 and Strehls of 28%–35% in 0
5–0
7
V-band seeing. Middle row: the same data as the top row, except the images have been post-detection aligned (SAA) and the pixel
response function (PRF) has been removed. This improved image resolution by ~5–6 mas. Bottom row: the row above is magnified
by three times to better display the data of the middle row. These are the highest resolution deep images ever obtained to
our knowledge.
