Abstract

After publication of Price & Laibe (2015), we discovered a sign error in the second term on the right-hand side of equation (4). The equation should read: The sign error was propagated to equations (13), (45), (A1), (A2) and on both sides of (A12). The sign was given correctly in equation (27). The correct sign was also used in the code, so there was no adverse effect on the test results or conservation properties. We further note that the corresponding equation can be found with the correct sign in Laibe & Price (2014). Specifically, equation (13) in Price & Laibe (2015) should read.
