Using Bollert's formalism, Stjepan Mohorovičić (1922) made a different choice for some parameter and obtained metric (2h) with a printing error, which was corrected by Bollert (1922b) with another printing error, until a version without printing error was given by Mohorovičić (1923). In addition, Mohorovičić erroneously argued that metric (2b, now called Kottler–Møller metric) is incorrect, which was rebutted by Bollert (1922). Metric (2h) was rediscovered by Harry Lass (1963), who also gave the corresponding coordinates (2g) which are sometimes called "Lass coordinates". Metric (2h), as well as (2a, 2b), was also derived by Fritz Rohrlich (1963). Eventually, the Lass coordinates (2g, 2h) were identified with Radar coordinates by Desloge & Philpott (1987).
