MASER DAS 2 server

This is a das2.2 server, it provides access to space physics data sources using a two distinct HTTP GET based query protocols:

• The Das 2.2 service protocol
• The HAPI 1.1 protocol, a simplified time series cube service defined by the heliophysics API group.

Recent activity logs for your IP address are available.

Full use of this site requires a client progam capable of reading data in das2.2 stream format. Autoplot is a full-featured graphical for plotting many types of space physics data, including streams from this server. In addition custom applications, or data analysis programs can be written in IDL via the das2pro package, Python using the das2py module, or C using libdas2.

Since this server delivers information over HTTP, limited functionality is available using any standard web browser. Some example queries are provided below.

Das 2.2 Service Queries

• Data Source List -- To download a list of all data sources known to this server use the following URL:
  
  https://voparis-das-maser.obspm.fr/das2/server?server=list
  
  
• Peer List -- To download a list of other das2 Servers known to this site use the following URL:
  
  https://voparis-das-maser.obspm.fr/das2/server?server=peers
  
  
• Dataset Definition -- To gather basic information on a datasource enter a URL with the pattern:
  
  https://voparis-das-maser.obspm.fr/das2/server?server=dsdf&dataset=DATA_SET_NAME
  
  Where the DATA_SET_NAME is one of the file paths provided by a data source list query. For example:
  
  https://voparis-das-maser.obspm.fr/das2/server?server=dsdf&dataset=Examples/Spectra
  
  
• Data Download -- To download data as either a Das2Stream or QStream enter a URL with the pattern:
  
  https://voparis-das-maser.obspm.fr/das2/server?server=dataset&dataset=DATA_SET_NAME&start_time=BEGIN&end_time=END
  
  Where the START and END are time strings. Though may time formats will work with most data sources, ISO-8601 format strings are recommended, in general these look like YYYY-MM-DDTHH:MM:SS.sss where uneeded time fields may be omitted. For example:
  
  https://voparis-das-maser.obspm.fr/das2/server?server=dataset&dataset=Examples/Spectra&start_time=1979-03-01T12:26:11&end_time=1979-03-01T12:29:24
