1° If the population is less than or equal to 500, a = 1;
2° If the population is greater than 500 and less than 200,000, a = 1 + 0.38431089 x log (population/500);
3° If the population is equal to or greater than 200,000, a = 2.
The population taken into account is determined in accordance with Article L. 2334-2.
