More thesis writing to get the Doppler shift to spectral profile calculations done. Have got through the theory and am now onto the actual instrument stuff - projection onto pixels equation and instrument profile...

Oh, and an email or two between me and IS in the form of Jeremy Yates about another Keter disaster, which has probably wiped out all the current runs... the important Uranus ones as well as the Grodent ones etc... Keter is likely to be shut down before I could rerun them all, which really ruins it.
