Abstract
We present a profile constrained geometry fit (PCGF) method for shower geometry reconstruction implemented in the Pierre Auger Observatory analysis chain. It is used to reconstruct low-energy extensive air showers ($3 \times 10^{15}$ eV $< E <$ $10^{18}$ eV) detected by the high elevation Auger telescopes (HEAT). The method is proven to be particularly important for events with signal dominated by Cherenkov light. The precision of the reconstruction is evaluated using full Monte Carlo simulations of the showers and telescopes. Simulations are compared to the data, and the results are discussed. A preliminary measurement of the energy spectrum in the second knee region is presented.
