  The Large Area X-ray Proportional Counter (LAXPC) instrument on-board
AstroSat has three nominally identical detectors for timing and spectral
studies in the energy range of 3--80 keV. The performance of these detectors
during the five years after the launch of AstroSat is described. Currently,
only one of the detector is working nominally. The variation in pressure,
energy resolution, gain and background with time are discussed. The
capabilities and limitations of the instrument are described. A brief account
of available analysis software is also provided.
