Links to all the screen/Target comparisons I've done so far.
If you don't want to take my word for it, you can perform your own comparisons; I highly recommend Chrissie's excellent Doctor Who transcripts if (like mine) your memory cheats.
The Doctor Who Reference Guide is also a useful if excitably written resource for this.
