Detailed Description

Millepede-II (binary) record.

Containing information for local (track) and global fit.

The data blocks are collected in two arrays, a real array (containing float or double values) and integer array, of same length. A positive record length indicate float and a negative one double values. The content of the record is:

*         real array              integer array
*     0   0.0                     error count (this record)
*     1   RMEAS, measured value   0                            -+
*     2   local derivative        index of local derivative     |
*     3   local derivative        index of local derivative     |
*     4    ...                                                  | block
*         SIGMA, error (>0)       0                             |
*         global derivative       label of global derivative    |
*         global derivative       label of global derivative   -+
*         RMEAS, measured value   0
*         local derivative        index of local derivative
*         local derivative        index of local derivative
*         ...
*         SIGMA, error            0
*         global derivative       label of global derivative
*         global derivative       label of global derivative
*         ...
*         global derivative       label of global derivative
