From the images you have selected, it will compose a mosaic with several resolutions (HEALPix tessellation), and organize them to allow their progressive display in Aladin. Now, we provide a new tool to build an all- sky view with your own images. The maps are constructed by mosaicing individual images. To improve on this capability, some catalogs and maps have been built from many surveys (e.g., DSS, IRIS, GLIMPSE, SDSS, 2MASS) in mixed resolutions, allowing progressive display. This all- sky view is particularly useful for visualization of very large objects and, with coverage of the whole sky, maps from the Planck satellite. Bonnarel, F.įrom the need to extend the display outside the boundaries of a single image, the Aladin team recently developed a new feature to visualize wide areas or even all of the sky. Aladin Lite is powered by HTML5 canvas technology and is easily embeddable on any web page and can also be controlled through a Javacript API. It allows visualization of image surveys (JPEG multi-resolution HEALPix all- sky surveys) and permits superimposing tabular (VOTable) and footprints (STC-S) data. Aladin Lite: Lightweight sky atlas for browsersĪladin Lite is a lightweight version of the Aladin tool, running in the browser and geared towards simple visualization of a sky region.
