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
*

Special data block (other/debug information). Contains no local derivatives and (error) SIGMA is negative (-Number of SPecial data words).

*         real array              integer array
*         0.0                     0                   -+
*         -float(NSP)             0                    |
*         special data            special data         | special block (2+NSP words)
*         special data            special data         |
*         ...                                         -+
