I am building a portal for ASTRON Data and I am trying to embed the ESASky Javascript API in an ReactJS application?
Has anybody ever tried that and has some examples?

Hi,

Are there any plans in translating ESASky to German? I am planning to introduce ESASky in Austria, and it would tremendously help, if the interface would be in German.

I was wondering if it would be possible to add a way to upload my own sky maps to view them as a layer among the different sky options. I deal with a lot of equirectangular maps that are in either ra/dec or galactic coordinates that would be interesting to see along with surveys and even to quickly investigate overlapping areas of interest. If there was a simple option to upload a jpg or png when creating a new row under sky select and specifying if it is in ra/dec or galactic that would be amazing. I would use it to plot sky models but I imagine others could use it to plot points of interest, observing footprints, or their own images. For example, in figure 9 of this paper there are some maps that (if plotted fully 90 to -90) could be simply mapped into ESA sky. If all maps are required to be full-sky as a standard it would likely be easier to integrate.

One of ESASky's many excellent features is the dialogue box shown for an object in a Gaia EDR3 catalogue overlay on some other sky which generates, for example, a SIMBAD query. The query generated e.g.

http://simbad.u-strasbg.fr/simbad/sim-coo?&Coord=84.669d-69.099d&CooFrame=FK5&Radius=2&Radius.unit=arcmin

specifies coordinates to 3 significant figures. This is not enough to have the correct star at the top of the resultant list in a crowded field. Another couple of figures would probably do the trick.

While we're at it, one more little thing. In the Chandra X-ray Observatory table, the final column on the right is "Duration" which is in seconds rather than the ksec units shown in the column header.

The line style is missing from the Chandra X-ray Observatory Style dialogue box and no field-of-view outlines appear. All the other imaging instruments I've tried are OK.

Would be nice to have a view option to overlay constellation names and borders along with the co-ordinate grid.

Would it be possible to add the PanSTARRS DR1 color map from CDS (http://alasky.u-strasbg.fr/Pan-STARRS/DR1/color-i-r-g/) to the tool? It seems to me that it has a wide sky coverage and substantially better image quality than DSS-2 so it would be great to be able to use it as optical background for most investiations in the tool, although unfortuantely it is not available.

Hi,

Congratulations on the tool. I find it very very useful.

I recently discovered a huge list of HiPS maps produced by the Centre de Donnees Astronomiques from Strasbourg (https://aladin.u-strasbg.fr/hips/list) and I wondered whether it would be possible to load any of those maps in ESASky by providing the URL of the HiPS, as listed in the website or in any other even easier way. That would allow a lot more discoveries to be made using those maps, which currently only can be seen in Aladin Desktop I think.
