    This bank contains summary information for a single-photon PCA run.  The
    data is used by the MPC processor to generate the Multiphoton PCA walk
    distribution.

Notes
-----

1)  The data is stored as a repeating table of floating point numbers.  The
    first word of actual data is located at (KPCAS_STATUS_WORDS+1).  Mnemonics
    have been set up to assist in reading the data.  Assume that you are
    looking at data for the i'th PMT.  The data is then stored in words:

KPCAS_STATUS_WORDS+(i*KPCAS_WORDS_PER_LINE)+...

  +1  F     KPCAS_TUBE             Snoman PMT number
  +2  F     KPCAS_HITS             Number of times tube was hit during PCA run
  +3  F     KPCAS_QHS              Average QHS of PMT
  +4  F     KPCAS_TAC              Average TAC of PMT
  +5  F     KPCAS_POS_X            X position of PMT
  +6  F     KPCAS_POS_Y            Y position of PMT
  +7  F     KPCAS_POS_Z            Z position of PMT
  +8  F     KPCAS_OCC              Occupancy of PMT during PCA run
