The fortran code to handle old-style bias correction updates that was converted from Met Office IDL code has a couple of bugs in it.
At some point it would be good to rewrite the code so that it reads what is required from the Bstat and biasdata files, rather than hard-coding in the Fortran, which leads to mistakes when this is set up for new satellite instruments.
In the meantime, the calc_bias.f90 code needs to be modified for all instruments other than ATOVS to ensure that bias corrections are updated for the outermost scan positions. The number of channels for ATMS is also incorrect, as is the definition of the scanline centre and the stratospheric channel which should be scan-bias-only corrected should be 15 and not 34.
