Analysis of the Greenland icesheet experiment in terms of new gravitational forces

We present an analysis of the anomalous gravitational attraction found in the Greenland icesheet experiment. If the anomalous gradient is due to the existence of a single new, attractive, force, then the force has a range between 225 m and 5.40 km and a coupling constant between 2.4% and 3.5% that of newtonian gravity, with a best fit of about 805 m and 3.1%, respectively. From our procedure, the chi-squared analysis describing the quality of any fit to parameter values can be immediately scaled if a fraction of the gravitational anomaly is actually due to density anomalies in the bedrock.
