Asteroseismic data for our sample of 415 objects have been obtained by the Kepler mission in short (58.5s) cadence, and light curves span from 30 up to more than 1000 days. The spectroscopic parameters are based on spectra taken as part of the Apache Point Observatory Galactic Evolution Experiment (APOGEE) and correspond to Data Release 13 of the Sloan Digital Sky Survey. We analyze our data using two independent Teff scales, the spectroscopic values from DR13 and those derived from SDSS griz photometry. We use the differences in our results arising from these choices as a test of systematic temperature uncertainties and find that they can lead to significant differences in the derived stellar properties. Determinations of surface gravity (logg), mean density (<ρ>), radius (R), mass (M), and age (τ) for the whole sample have been carried out by means of (stellar) grid-based modeling. We have thoroughly assessed random and systematic error sources in the spectroscopic and asteroseismic data, as well as in the grid-based modeling determination of the stellar quantities provided in the catalog. We provide stellar properties determined for each of the two Teff scales. The median combined (random and systematic) uncertainties are 2% (0.01dex; logg), 3.4% (<ρ>), 2.6% (R), 5.1% (M), and 19% (τ) for the photometric Teff scale and 2% (logg), 3.5% (<ρ>), 2.7% (R), 6.3% (M), and 23% (τ) for the spectroscopic scale. Description: The catalog consists of stars with detected solar-like oscillations in Kepler short-cadence data as reported in Chaplin+ (2011Sci...332..213C) and with spectroscopic observations from the APOGEE-1 survey (Majewski+ 2017AJ....154...94M). APOGEE spectra cover the H band, between 1.51 and 1.7um, at a resolution R=22500. This work extends the first APOKASC red giants catalog presented in Pinsonneault+ (2014, J/ApJS/215/19) to include 415 dwarf and subgiant stars. It is based on global seismic parameters Δν and νmax obtained from Kepler short-cadence asteroseismic data with length of light curves spanning from 30 up to 1055 days. File Summary:
