In [6296] I wrote, about the effects of aberration- "This can cause a worst-case difference of about 0.7 �, between a star-star distance and its value six months later. John Karl has tabulated his star-star distance to 0.1 �, but the numbers can not be relied on to anywhere near that precision." But I labelled the units wrong. It should, of course, have been- "This can cause a worst-case difference of about 0.7 ', between a star-star distance and its value six months later. John Karl has tabulated his star-star distance to 0.1 ', but the numbers can not be relied on to anywhere near that precision. Sorry about that.
