In 2009 Kokotov, Korotkin and Zograf gave a formula for the class of the
Hodge bundle on the Hurwitz space of admissible covers of genus g and degree d
of the projective line. They gave an analytic proof of it. In this note we give
an algebraic proof and an extension of the result.Comment: 8 pages; misprints correcte
