[pstricks] uput and \SpecialCoor

[Werner Grundlingh]

Your \uput is malformed. The syntax is
  \uput*{<labelsep>}[<refangle>]{<rotation>}(<x>,<y>){<stuff>}
Some of the components are optional (even though they are braced). You
*might* be after an interface that resembles
  \uput[d]{0}(! 2 1.4 mul 1.8){$t$}
I don't really know what you're after though, so my selection could be
completely wrong.

As reference, see the pstricks
documentation<http://mirror.ctan.org/graphics/pstricks/base/doc/pstricks-doc.pdf>,
specifically section *24 Placing and rotating whatever* on page 43.
