Diminished 7ths Csharp and D?

Can you please tell me the notes for diminished sevenths, in the keys of Csharp and D, for the piano?

A diminished seventh on C# consists of C#, E, G, and Bb.
A diminished seventh on D consists of D, F, Ab, and B.
A diminished seventh on Eb consists of Eb, F#, A, and C.

Those are the only possible diminished sevenths.
If you make a diminished on any other note, you will get an inversion of one of the diminished sevenths listed above.

C#-E-G-Bflat
D-F-Aflat-Cflat
