****************************************************** PR # 6 SNR 0540-693 is similar in age and luminosity to the Crab Nebula and itspulsar, although the SNR shell is visible (optically and with ROSAT) and thepulsar pulse profile is very different. Calibration aims including timingchecks on a fast pulsar and separation of spatially unresolved, spectrallydistinct components. Scientifically, we will determine the pulsed, non-pulsedsynchrotron, and thermal remnant spectra, and map the surrounding diffuseemission. ******************************************************
