Ticket abuse cleaned up

2010 Oct

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 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.

Updated IDL Client

2010 Sept 20

There have been a number of new keywords added the VSO IDL client, this summer, including:

For VSO_SEARCH() :
    NEAR       : get data 'near' a given time.
    /LATEST    : get just the most recent record
    LEVEL      : only return a given processed level (eg, '0', '1')
    PSCALE     : only return a given pixel scale (in arc seconds)
    PIXELS     : only return images of a given number of pixels
    RESOLUTION : only return data of a given level of reduction

For VSO_GET:
    /RICE     : retrieve Rice-compressed data, where available.
    /NORICE   : do not retrieve Rice-compressed data.  (currently the default, but may change as support broadens)
    SITE      : specify which SDO data distribution site to use.
    EMAIL     : specify an e-mail address to use to download 'staged' data.
    /STAGING  : prefer 'staged' data over immediate URLs.
    FILENAMES : will contain the location of any files downloaded

See ​the IDL client documentation for additional details about how these new search terms are handled.

The VSO Documentation Site has been updated

2010 Sept 16

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.
