tsc_Mta

MTAs (Mean Turned Angles) are observations which are made from the average of the 'turned angles' from the backsight to a known point.   The observations used all "belong" to a single station and any target differences are taken into account.

Each MTA consists of the following:

• • Identification of the point in question, the target used and which station the observations are from.

  • The mean values representing the averaged accumulation of F1 and F2 observations.

  • A count of the number of observations that contributed.

Constructor

tsc_Mta (tsc_Station& station, tsc_Point& known, const double& backBearing);

Constructs an MTA for the specified point observed from the specified station with backbearing.
