Release of JUDO2 2.0
JUDO2 is a web-application tool to browse astronomical images
taken by various satellites and ground-based
observatories projected on the celestial sphere.
Now,
JUDO2 being fully
updated with new user-interface, added new satellite images, field-of-views (foot-prints) and observation information,
and, "
JUDO2 2.0 " has been released!
The following satellite images, foot-prints and observation information are added:
Hitomi images and foot-prints, Akari IRC pointing images and foot-prints, Chandra, NICER and NuSTAR foot-prints.
This link
gives
SDSS optical image of the Perseus clusters of galaxies, being superposed with
Hitomi SXS image and foot-prints, and Chandra and XMM foot-prints.
If you click the "Start UDON2 for Quick Look" button in the right-hand side,
you can quick-analyze the SXS data (select region, extract and display the light-curve and spectrum).
Since NICER has a short exposure time for each pointing and there are many pointings for a single target,
we made observation list page for each target. For instance,
this link gives a PSRB1937+21 observation list, from which links are made to HEASARC archival data.
The figure in the right-hand side is an LMC mosaic-image by Akari IRC,
with the background WISE all-sky IR image.
Clicking the IRC observation number displayed in the bottom part,
observation information page is displayed, from which archive data are linked.
