Would it be possible to link an ESASky session with my dropbox account such that all the data I select are sent to my drobpox account instead of directly downloading it to my computer?

Hi again,

I have been trying to identify a super nova in ESA Sky and I cannot localize the archival images where the SN is because when I explore the browse products, they do not appear superimposedon the background image with the correct rotation but instead they appear as extra windows on top witha default orientation. Would it be possible to have the images appear on top of the background image with the correct rotation angle and size? That would make the exploration of imaging data actually possible on the interface, currently one just has to end downloading all the images and doing the work offline in ds9, which is not so great because then you loose the possibility of overplotting catalogues, publications, etc..

Do you think this would be possible?

Hello,

I noticed that (mainly local) galaxies have publication assigned to single clumps or even stars. Currently, it is not possible to select *all* publications for a single local galaxy, but one has to select each sub-catalog of publications.

Here is an example:

Search for NGC 5253, which is a irregular local dwarf galaxy. For this galaxy, about 2100 publications are available, however, they are distributed over the whole galaxy as shown in the image below (named "NGC5253 NC1" or "NGC5253 NC245", etc). There is no option to select all publication linked to this particular galaxy, which would be very useful.

There are at least two user friendly solutions to this:

1) Let the user select different publication entries by dragging a box around them

2) Group the publications together depending on the level of zoom (i.e., zoom in to split the publication into multiple groups depending on the targeted location in the galaxy; zoom out to have only one group with all the publications linked to a galaxy).

Best,

Andreas

In the educational activities, students sometimes have trouble, and waste a lot of time, downloading the target list from the server and uploading it to ESASky. To simplify this, we could provide the target lists directly when ESASky is loaded, either as a menu in the 'Target list' button, or maybe as part of a permalink.

In the teachers' workshop at ESTEC it was suggested that a very useful feature would be the possibility to visualize several skies/sky regions at the same time. It is something that had already been suggested before. This would make comparisons easier between different objects in the same sky, or between observations of the same object by different missions or in different passbands. 

I can think of two possibilities: via tiling (dividing the window into smaller pieces) and via transparency. Both are implemented in Aladin Desktop. Maybe we should think of possible issues with the data panel interaction, though...

Here are some visualizations suggestions I think they can be useful at preparing observations:

• Allow defining the FoV orientation (rotation of the foV)
• Allow flipping the FoV
• Allow toggling show/hidden selected sources

Just thought -- if this easy to do -- can we put in the accepted JWST GTO and ERS target lists as a catalog in ESASky??? By Nov 30 2017 when Cycle 1 is released ?

During the commissioning of the MEGARA instrument at GTC, ESAsky was used. It was very useful, but it would be even more with the capability of uploading DS9 region files, mainly used to represent instruments focal planes.

Other formats as VO would be nice, but ds9 is still broadly used in the astronomical community
