question: private void checkLimits ( float temp , float year ) { if ( Float . isNaN ( overall_max_temp_ ) || temp > overall_max_temp_ ) overall_max_temp_ = temp ; if ( Float . isNaN ( overall_min_temp_ ) || temp < overall_min_temp_ ) overall_min_temp_ = temp ; if ( Float . isNaN ( overall_max_year_ ) || year > overall_max_year_ ) overall_max_year_ = year ; if ( Float . isNaN ( overall_min_year_ ) || year < overall_min_year_ ) overall_min_year_ = year ; }
target:  See if these values for temp and year are outside of our current notion of how large our data space is. <p>
