Does anybody have a clue wat the "BSC", in the dimension specification for Small Outline packages for ICs actually means.

I need the dimensions of the spacing between two pins in a SOT 23-5 package IC. However, the dimensions are expressed in "0.55 BSC" etc. Therefore, umless I figure out what BSC is, I'm stuck at square one. My efforts on Google, so far have returned futile results.
