  * @brief The categories of random number generated.
  *
  * The values of the fields are carefully chose numbers
- * These are values adviced by NR to use on page
- * 348 in the first table. We used selected 4 numbers
- * and know that they produce no correlation at all
- * for the 4 different processes.
+ * the numbers are very large primes such that the IDs 
+ * will not have a prime factorization with this coefficient
+ * this results in a very high period for the random number
+ * generator.
  * Only change when you know what you are doing, changing
  * the numbers to bad values will break the random number
  * generator.
  * In case new numbers need to be added other possible
  * numbers could be:
- * 4162943475, 3874257210, 2654432763
+ * 4947009007, 5947309451, 6977309513
