Description:
A pulse-time history of PSR B0540-69 is reported, based on the
analysis of an extended data set including ASCA, BeppoSAX and RXTE
observations spanning a time interval of about 8 years. This interval
includes also the epoch of the glitch episode reported by Zhang et al.
(2001ApJ...554L.177Z 2001ApJ...554L.177Z).
The log of all observations include:
RXTE observations between 1996-03-08 and 2001-03-14: data from PCA
only, accumulated in "Good Xenon" telemetry mode, time-tagged
with a 1us accuracy;
ASCA observations between 1993-06-13 and 1999-11-03: data from GIS
Beppo-SAX observations between 1996-10-26 and 2000-02-19: data from MECS
