crsx and crsy represent the location on the map. crsteetimesyn, crslessonsyn, crshandicapsyn and crscompetitionsyn indicate whether the course allows these bookings or allows the registration of qualifying cards (to improve the handicap).

if a wrong authorisation code is provided, the list of courses in the resultset will contain 0 records.
