Can timing analyses be done with ROSAT?
(7/15/91)
It depends upon the expected signal frequency. If it corresponds to the order of milliseconds, or to the order of many hours, the answer, at least in principle, is 'yes'. If the expected frequency corresponds to ANY time near the fundamental periods of the satellite (orbit, wobble, earth-block, ...), the answer is an absolute 'no'. The PSF is sufficiently good that the thin wire grid can occult a point source. Furthermore, each of the quantities needed (aspect solution, wire position seen by the PSPC, ...) to deconvolve the effect of the wire grid is NOT known sufficiently accurately to make the problem tractable.
