same heigth of markups

[Stefan Thomas]

Dear Lilypond-users,
I would like to have, in the below quoted example, the "Dsechsvier" on the same heigth as the "T".
How can I get this?
Thanks for Your help,
Stefan

\version "2.11.60"

Dsechsvier =  \markup { D \super { \combine \raise #1.1  6   4   }  } 
T =  \markup {T}
\new Staff \relative c {  \clef bass c1_\T c1_\Dsechsvier }
\layout{
  \context { \Staff  \override TextScript #'staff-padding = #3 }  }
