Parameters for all 402 new overdensity candidates found across 15 ORELSE fields with their redshifts, transverse positions, fitted masses, and spectroscopic fractions. The parameters given in this file are ORELSE field, field ID number, number of points used in the Gaussian fit, redshift mean and dispersion and associated errors, equatorial coordinates, estimated total mass and associated errors, and spectroscopic fraction. The candidates were cut by spectroscopic fraction such that only those with a spectroscopic fraction of 0.05 were included. All logarithms are base 10. (1 data file).
