	abstract = {Let X be a matrix of full column rank, and let D be a positive definite diagonal matrix. In a recent paper, Stewart considered the weighted pseudoinverse X{\textdagger}D = (XTDX)-1XTD and the associated oblique projection PD = XX{\textdagger}D, and gave bounds, independent of D, for the norms of these matrices. In this note, we answer a question he raised by showing that the bounds are computable.},
