    11= Virtual Solar Observatory = 
    22 
     3Welcome to the Virtual Solar Observatory!   
     4 
     5The VSO is a tool for investigating the physics of the Sun.  Users may search existing databases for terrestrial and space-based observations, hiding the details of where the data is and what’s needed to get it.  A researcher can use the VSO to search across multiple instruments and events, to find datasets of interest, and having done that, transparently download them to their workstation.  
     6 
     7There are many ways to use the VSO to search and download data. The main two ways are:   
     81.      Via our [http://virtualsolar.org web interface] and 
     92.      Via [http://www.lmsal.com/solarsoft/ssw_whatitis.html SolarSoft] in IDL   
     10 
     11Because we publish our API, users can use their favorite programming language to access the VSO including [http://http://sunpy.org/ SunPY] and  
     12[http://docs.virtualsolar.org/WSDL WSDL]. 
     13 
     14The VSO web and data interfaces are a singular model mirrored across multiple sites such as the NASA Solar Data Archive Center, the National Solar Observatory and the Smithsonian Astrophysical Observatory. The data archives themselves are distributed, residing with the groups that designed, built and used the instruments to collect the data; they possess the expertise required to fully exploit the data.

     16== Data Products == 
     17 
     18We have observations available from sources as diverse as NASA’s space-bourne Solar Dynamics Observatory and the ground-based GONG instrument.  Observations go back nearly 100 years, such as from the Mt Wilson 60ft spectro-heliograph.  We are proud of our international partnerships and we are always looking to serve more data whenever possible.   
     19  
     20A current list of our data providers can be found here: 
     21[http://vso.nascom.nasa.gov/cgi-bin/show_details.pl?keyword=PROVIDER] 
     22 
     23Our data is generally provided as FITS files but may also be in other standards, such as XML or HDF.

    11 We are currently in the process of moving all of our documentation to a centralized location.  Please excuse the inconvenience while we rearrange, and if you have an immediate issue, please feel free to  [wiki:ContactUs contact the site admin].

    19 We've had to shut down allowing anonymous posting of tickets until we can find a good way to prevent spambots from abusing it.  If you're a vso user, and would like an account on here to submit tickets, please contact [wiki:People/JoeHourcle Joe Hourclé].  We also deleted 16,000 spam tickets, so it's possible that we might've deleted a legitimate ticket ... if you submitted something that's no longer there, please let us know.

    22 === Updated IDL Client === 
    23  
    24 2010 Sept 20 
    25  
    26 There have been a number of new keywords added the VSO IDL client, this summer, including: 
    27  
    28 {{{ 
    29 For VSO_SEARCH() : 
    30     NEAR       : get data 'near' a given time. 
    31     /LATEST    : get just the most recent record 
    32     LEVEL      : only return a given processed level (eg, '0', '1') 
    33     PSCALE     : only return a given pixel scale (in arc seconds) 
    34     PIXELS     : only return images of a given number of pixels 
    35     RESOLUTION : only return data of a given level of reduction 
    36  
    37 For VSO_GET: 
    38     /RICE     : retrieve Rice-compressed data, where available. 
    39     /NORICE   : do not retrieve Rice-compressed data.  (currently the default, but may change as support broadens) 
    40     SITE      : specify which SDO data distribution site to use. 
    41     EMAIL     : specify an e-mail address to use to download 'staged' data. 
    42     /STAGING  : prefer 'staged' data over immediate URLs. 
    43     FILENAMES : will contain the location of any files downloaded 
    44 }}} 
    45  
    46 See [http://docs.virtualsolar.org/IDL the IDL client documentation] for additional details about how these new search terms are handled. 
    47  
    48  
    49 === The VSO Documentation Site has been updated === 
    50  
    51 2010 Sept 16 
    52  
    53 This website hadn't been updated due to a combination of security policies, an untested upgrade locking us out of the system, and general neglect as we worked towards getting the SDO data distribution system up.  In our new location, however, we can once again allow the public to submit trouble tickets;  it might take us a while to full review, updated and/or close the many-years stale tickets, and to add tickets to accurately reflect the current work in progress. 
    54

    56 === Revised VSO WSDL === 
    57

    64 === SDO Test Data Released === 
    65  
    66 2010 May 25 
    67  
    68 AIA and HMI test data have been released for scientists to see the headers and to test compatibility with their tools;  is not fully calibrated and should not be used for publication at this time.  EVE integration into the VSO is forthcoming.

     39This website hadn't been updated in some time, but we are in the process of tightening up our categories to make the documentation more helpful.  Please bear with us as we construct new pages.
