  • [year]: The year in format YYYY
  • [day]: The day of the year, from 001 to 365/366
  • [station]: The name of the station, one of the following - ADCS,BUCE,BUZE,CONB,CRCL,HIST,PGNL,RMSR,ROSP,ROSU,TECC,TIRG,TUDO,VLDS,VRAP
  • [parameter]: The type of index, can be S4 or sigphi
  • [filename]: The name of the data file, which has the format [satellite_name][hour]_[time_interval]_s4.out (e.g. "C23r_45_s4.out"). The hour is denoted with letters from 'a' to 'x', 'a being 00:00:00 and 'x' 23:00:00. [time_interval] can be 15 for time interval between hh:00:00.0 and hh:14:59.9, 30 for time interval between hh:15:00.0 and hh:29:59.9, 45 for time interval between hh:30:00.0 and hh:44:59.9 and 60 for time interval between hh:45:00.0 and hh:59:59.9.

Example :

For obtaining the S4 index data for the year 2020,day 326,station BUZE, sattelite G13, time interval 18:00:00.0 - 18:15:00.0 the query is:
http://hephaistos.spacescience.ro/resources/2020/326/SCIN/BUZE/S4/G13s_15_s4.out

One can use for example a machine-to-machina command such as "curl" to retrieve the products: curl --user :http://hephaistos.spacescience.ro/resources/2020/326/SCIN/BUZE/S4/G13s_15_s4.out An user name and a password has be provided by the service admin.

Multiple parameters can be obtained using repeated queries.
