[NTG-context] Eliminate space between float and caption

I am trying to find a way to reduce/eliminate the space between a figure and a caption. The default amount looks rather large to me: larger than the spacing between the caption and the body text. I tried to use the inbetween option in \setupcation, but I can only seem to increase the space between the figure and caption and not reduce it. I saw a reference to details.pdf in the mailing list about more advanced examples of captions, but when I went to www.pragma-ade.com/temp the page no longer exists and I couldn't find details.pdf. Thanks, Mike
