Query: An extension of the Gluckstern formulas for multiple scattering:
  analytic expressions for track parameter resolution using optimum weights   Momentum, track angle and impact parameter resolution are key performance
parameters that tracking detectors are optimised for. This report presents
analytic expressions for the resolution of these parameters for equal and
equidistant tracking layers. The expressions for the contribution from position
resolution are based on the Gluckstern formulas and are well established. The
expressions for the contribution from multiple scattering using optimum weights
are discussed in detail.
