**Exact Finite-Size Scaling and Corrections to Scaling in the Ising
Model with Brascamp-Kunz Boundary Conditions**

The Ising model in two dimensions with the special boundary
conditions of Brascamp and Kunz is analysed.
Leading and sub-dominant scaling behaviour of the Fisher
zeroes are determined exactly.
The finite-size scaling, with corrections,
of the specific heat is determined
both at the critical and pseudocritical points.
The shift exponents associated with scaling of the pseudocritical
points are not the same as the inverse correlation length
critical exponent.
All corrections to scaling are analytic.
