The PN quantum efficiency file has the same format as the MOS files.
The only difference is in the CCD extensions where there are only
two pattern dependent columns: QE_0 giving the QE in single-pixel events
as a function of energy and QE_1 which gives the QE in double-pixel
events. The latter is the sum of the QE in patterns 1-4.
