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

		bool	doublePrec = false,
		unsigned int	aSize = 2000
	)

Create binary file.

Parameters

[in]	fileName	File name

                        :
    binaryFile(fileName.c_str(), std::ios::binary | std::ios::out), intBuffer(), floatBuffer(), doubleBuffer(), doublePrecision(
        doublePrec) {
  intBuffer.reserve(aSize);
  intBuffer.push_back(0); // first word is error counter
  if (doublePrecision) {
    doubleBuffer.reserve(aSize);
    doubleBuffer.push_back(0.);
 
  } else {
    floatBuffer.reserve(aSize);
    floatBuffer.push_back(0.);
  }
}
