We recorded high signal-to-noise (S/N≥200) spectra of RC stars over the 4750-5950Å range at a resolving power 5500. The target stars are distributed across the great circle of the celestial equator. Radial velocities were obtained via cross-correlation with IAU radial velocity standards. Atmospheric parameters were derived via χ2 fit to a synthetic spectral library. A large number of RC stars from other surveys were re-observed to check the consistency of our results and the absence of offsets and trends. Description: File arcs2f.dat contains the name, available photometric, additional spectroscopic and calculated parameters of observed 245 Red Clump stars that are observed at only one epoch. File arcs2s.dat contains same data for 60 Red Clump stars that are observed in an additional second epoch. File Summary:
