  "abstract": "We present the Bayesian Asteroseismology data Modeling (BAM) pipeline, an automated asteroseismology pipeline that returns global oscillation parameters and granulation parameters from the analysis of photometric time-series. BAM also determines if a star is likely to be a solar-like oscillator. We have designed BAM to specially process ${\\it K2}$ light curves, which suffer from unique noise signatures that can confuse asteroseismic analysis, though it may be used on any photometric time series --- including those from ${\\it Kepler}$ and ${\\it TESS}$. We demonstrate the BAM oscillation parameters are consistent within $\\sim 1.53\\%\\ (\\mathrm{random}) \\pm 0.2\\%\\ (\\mathrm{systematic})$ and $1.51\\%\\ (\\mathrm{random}) \\pm 0.6\\%\\ (\\mathrm{systematic})$ for $\\nu_{\\mathrm{max}}$ and $\\Delta \\nu$ with benchmark results for typical ${\\it K2}$ red giant stars in the ${\\it K2}$ Galactic Archaeology Program's (GAP) Campaign 1 sample. Application of BAM to $13016$ ${\\it K2}$ Campaign 1 targets not in the GAP sample yields $104$ red giant solar-like oscillators. Based on the number of serendipitous giants we find, we estimate an upper limit on the average purity in dwarf selection among C1 proposals is $\\approx 99\\%$, which could be lower when considering incompleteness in BAM detection efficiency, and proper motion cuts specific to C1 Guest Observer proposals.",
