Version History

Version 2.1		UVI Online Search Tool Ver 2.1 available for public access on June 24th, 2005. Image-derived parameters were added as search options. These parameters are estimated by automated algorithms that examine the information content of each image. Search parameters include energy deposited in the auroral oval, the overall quality of the image, and how much of the auroral oval is seen within the UVI field of view. IMPORTANT: Since these parameters are estimated from automated, unsupervised algorithms they should be used to guide searches only. Please contact a UVI team member if detailed scientific analysis using these parameters is required. Back to Top
Version 2.0		UVI Online Search Tool Ver 2.0 available for public access on Dec 1st, 2004 A data download service was added to the system allowing users to download digital UVI data. Users can download either Full Resolution data or 10 Minute Resolution data. OST-Viewer v1.0 was also provided for download. This is a simple IDL tool that lets users view downloaded UVI data.

Version 1.4		UVI Online Search Tool Ver 1.4 available for public access on July 25th, 2003. OMNI solar wind data and the Akasofu epsilon parameter have been added to the database. The search page has been modified to search based on the new data. The search page has also been modified to let the user specify day of year (DOY) instead of a month/day combination. Back to Top
Version 1.3		UVI Online Search Tool Ver 1.3 available for public access on June 2nd, 2003. The record selection algorithm was changed to give preference to full-integration LBHL and LBHS in each 10-minute time period. This primarily affects the thumbnails displayed. Now, if you see a background image it indicates that there were no other images available in that 10-minute period. This update also corrected problems with the on-earth calculations and removed the RA/DEC search options. Back to Top
Version 1.2		UVI Online Search Tool Ver 1.2 available for public access on September 9th, 2002. The search page has been redesigned to allow a user to search for times when selected ground stations are in the UVI field of view. Maps are also available to help the user identify the observatories. As a by-product of this upgrade we've also replaced the previous (binary) On-Earth flag with an On-Earth percentage, in which you can specify, for example, that at least 75% of the UVI pixels be viewing the Earth.

Version 1.1		UVI Online Search Tool Ver 1.1 available for public access on June 7th, 2002. An important feature of this version is the inclusion of thumbnails of the auroral images, improving the usefulness of the result page. Without having to click on the browse image links to look at the images, the user will get to see the auroral thumbnails on the result page itself. In an effort to improve the quality of the data in the CSDS database, all background filter records (HOME, SHUTTER, UNKN) have been replaced with useful filter records (LBHL, LBHS, etc.) where possible. The database is currently fixed at a 10 minute resolution relative to the UVI database that is at approximately 37 second resolution. Records are selected at approximately 00, 10, 20, 30, 40, 50 minutes from the full resolution database and it is possible that this record may be a background record. The software that imports the data is now capable of selecting a useful record from the 10 minute period following the background record if one exists. It is possible that the entire 10 minute period may consist solely of background images, in which case, the first record of the 10 minute period is retained. Therefore, there are still some background images in the database. Back to Top
