LookData

This is a tool developed by the JSOC team for internet data searching and data queuing.

You can access it at: http://jsoc.stanford.edu/ajax/lookdata.html

The documents below describes how to get SDO data using lookdata tool.

1. "Find the Dataseries"

All JSOC data is stored in a database system ("DRMS") that references a large filing system ("SUMS"). All the data is stored in series. Each series represents a set of data of the same type. For example, data series "hmi.v_45s" contains HMI doplelograms. Read this to get more information.

To select data seies you can use "Seriesname filter" input field on "Series select" tab. For example, to get all data series for SDO/AIA data you should enter 'aia' ('hmi' - to get HMI data series). If you know the series for your data, you can enter this field blank. The default value is "NOT ^dsds\.", because the namespace 'dsds' contains over 13,000 series, and is mostly old MDI data ported over from our Oracle system.

While the search for series is happening, the lookdata page will tell you that it is "processing", and offer you an "abort" button if you wish to stop the search. When the search is done, lookdata will tell you how many series matched your search, below the search text box.
