Measured the output power of the NPRO with an Ophir 20C-SH power meter (S/N 171175) to be 1.82 W.  This was
measured before the phase correcting EOM.
  1.82 W corresponds to 1.097 V on photodiode (-1797 counts)
     0 W corresponds to 0.068 V on photodiode (-111 counts)

    Pulling up the filter MEDM screen (H1PSLPMC_PWR_NPRO.adl), INMON was ~ -1765 counts.  So ~ -32 counts
were "missing".  I changed the offset to reflect this value.  The gain was taken to be -0.00101263150
(ie 1.82 W 1797 counts /).

    With these changes, the laser MEDM screen displays a value for the output power of the NPRO close to
the value measured with a power meter.
