0005  *
0006  *  Class to hold DB object for survey errors.
0007  *
0008  *  DB object contains the following:
0009  *    an unsigned 8-bit integer for the structure type
0010  *    an unsigned 32-bit integer for the detector's raw id
0011  *    an array of 21 floats for the error matrix of 6 alignment parameters
0012  *  The lower triangular of the error matrix is stored.
