ABSTRACT 
In this paper we derive and analyse a class of linearly implicit
schemes which includes the one of Feistauer and Kuˇcera (JCP 2007) [9]
as well as the class of RSIMEX schemes [4, 17, 27, 28]. The implicit
part is based on a Jacobian matrix which is evaluated at a reference
state. This state can be either the solution at the old time level as in
[9], or a numerical approximation of the incompressible limit equations
as in [30], or possibly another state. Subsequently, it is shown that this
class of methods is asymptotically preserving under the assumption of
a discrete Hilbert expansion. For a onedimensional setting with some
limitations on the reference state, the existence of a discrete Hilbert
expansion is shown.
