Software for calculating the baseline temperature minima using the method of photothermal units

This work developed software with the Java language to determine the photothermal unit depending on degree days. Using the software is the most reliable, and facilitates studies using photothermal unit. To construct the software were first determined parameters necessary inputs for the calculations is the number of data to be studied, the minimum, average and maximum temperatures, latitude, day and temperature range to which you want to verify that is the minimum core temperature. For each value of minimum basal Temperature (Tb) was calculated by the chosen degree days and UF, to then determine the mean and standard deviation. With this we calculated the coefficient of variation (cv) for each chosen Tb. After these calculations the software builds a graph for analysis of results, so the software does great contribution since it optimizes and automates the calculation of the minimum core temperature.
