Steps followed by the global time-derivative algorithm. After data acquisition and rectification, the exponential model is applied for each () position with the values of temperature for each time instant. As a result, a temperature function is obtained and the time derivate of the temperature function is the cooling function, which is averaged for each position of the matrix, obtaining a matrix of cooling rates.
