AKARI-CAS Explore tool updated
AKARI-CAS (AKARI Catalog Archive Server) Explore tool is updated with significant renovation. Whereas AKARI-CAS has been developed to query point sources in the AKARI Point Source Catalogs (PSC), you can, using the Explore tool, simultaneously display maps taken by various instruments around the point sources not only in the AKARI PSC, but also in other major catalogs. Thanks to "Aladin Lite", which enables you to browse easily and flexibly various colored survey maps, it became possible to display the AKARI/FIS All-Sky Survey Map. (AKARI/IRC (Infrared Camera) all-sky map data are to be released soon. ) This time, the maps of AKARI/FIS and WISE are added to the previously released map data (IRIS, 2MASS and DSS2) and catalog data (AKARI/FIS, AKARI/IRC, RC3, IRAS, IRAS FSC, and 2MASS).

Viking Lander 2 Mars seismology data released
Mars seismic data obtained by Viking Lander 2 mission in 1970's are released from DARTS. The original data were processed by UTIG and MIT independently. Therefore, there have been two different datasets in the world from the same measurement. The UTIG processed data were sent to ISAS together with the Apollo seismic data. The MIT processed data have been archived at NSSDC, which, unfortunatelly, do not seem to be widely used. At DARTS, we provide both datasets with technical description. To validate them, we have compared the two versions of the datasets. As a result of the comparison, they are found to be essentially identical, although formats are different. For instance, the famous figure published in the old report "Seismology on Mars" in 1977 (right, top) can be newly re-constructed using the MIT version of the data: DD030692_F3/8260, 8270, 8280, 8290, 8300 (right, bottom).
