             However, predictions for Q have mixed results when compared to the Micrometals Q-Curve Catalog found <a href="https://s3.amazonaws.com/micrometals-production/filer_public/7e/d0/7ed096a0-fe6e-4df1-9da9-e129c1ee73d2/q_curve_catalog_issue_h.pdf">HERE</a>.
             I suggest using their catalog for accurate Q prediction. It has been previously identified that Q values predicted using Micrometal's curve-fit equations do not reconcile with measured Q as discussed <a href="https://owenduffy.net/calc/toroid.htm">here</a>.
