Dear Jerry L.,

The 24Kx24K resolution images on ESASky have only been provided to guide the users toward the calibrated full-resolution Euclid images available using the link to the cosmos web site ( https://www.cosmos.esa.int/web/euclid/ero-public-release ) and are not made available as such. Your previous request had already been escalated to the Euclid Mission Manager and the answer I provided reflected his answer and the rules that have been set for access to these files (this answer also reflects the answer from the Mission Manager). Not all Euclid data products can currently be downloaded publicly. We apologize for any inconvenience this may cause.

Kind regards,

Deborah on behalf of the ESASky team

Dear Nadia,

Many thanks for your suggestion. We have added it to our backlog of tickets as a very nice feature to have in ESASky!

This is exactly the kind of input we are looking for from our users, so thanks again!
Best regards,

Deborah, on behalf of the ESASky team

Dear Jerry L.


Indeed, the ERO images from Euclid are not available to download from ESASky (this is also the case for the Hubble and Webb outreach images). However, links to access the images and download the data are available from the Euclid ERO page here: https://www.cosmos.esa.int/web/euclid/ero-public-release

Kind regards,

Dear Fanfan,

We are currently working with the eROSITA team to add DR1 data (catalogues and HiPS: background skies)! 


And the eROSITA team have already registered their HiPS in the IVOA, which means you can open the DR1 eROSITA HiPS in ESASky by doing the following: click on the skies icon (top left), select the + button and choose 'Browse HiPS Registry'. Then type erosita in the ID or Title columns and all of the DR1 HIPS provided by eROSITA are listed. Then click the + button to the left of each HiPS to display it in ESASky:

You can find more information on how to access the HiPS registry in ESASky here: https://www.cosmos.esa.int/web/esdc/esasky-interface#skies 


Many thanks for your feedback and we'll let you know when the rest of the eROSITA DR1 data is available in ESASky.


Kind regards,

Deborah

Dear ESASky user,

Many thanks for letting us know about this issue. Something had changed in the MAST TAP service, however, it should now be working again for you in ESASky.

Please let us know if you are still experiencing issues.

Best regards,

Deborah

Dear ESASky User,

Yes, it is possible to overlay a circle using CIRCLE, the central coordinates and radius (in degrees). E.g.:

{event: 'overlayFootprints', content:{'overlaySet': {'type': 'FootprintListOverlay', 'overlayName': 'test footprints', 'cooframe': 'J2000', 'color': 'red', 'lineWidth': 5, 'skyObjectList': [{'name': 'test footprint1', 'id': 1, 'stcs': 'CIRCLE ICRS 187.33912535049 -62.6616054228651 0.02', 'ra_deg': '187.287228500645', 'dec_deg': '-62.6876148176328'}]}}}

Here are some more examples of STCS strings (taken from the search tools information):

"BOX ICRS 11.421 41.764 10.071 41.765 10.079 40.864 11.411 40.863"

"POLYGON ICRS 9.97 41.04 11.13 41.94 11.45 42.0 11.34 41.51 10.15 40.53 9.79 40.80 9.97 41.03 9.97 41.03"

"CIRCLE ICRS 10.76 41.28 0.8"

In general, a BOX is the following:
BOX ICRS RA(1) DEC(1) RA(2) DEC(2) RA(3) DEC(3) RA(4) DEC(4).

A POLYGON can have more than 4 sets of coordinates: 
POLYGON ICRS RA(1) DEC(1).... RA(n) DEC(n).

And a CIRCLE has the coordinates and radius:

CIRCLE ICRS RA(1) DEC(1) Radius

Finally, I'm afraid the ESASky source code is not currently available.

I hope all this helps.

Kind regards,

Deborah on behalf of the ESASky team

We're happy to report that the issue has now been fixed and the Hubble and Webb images can again be viewed in ESASky!

Dear Casey,

We're happy to report that the issue has now been fixed and the Hubble and Webb images can again be viewed in ESASky!


This turned out to be a CORS issue with the CDN that has been fixed.

Many thanks for your patience and for reporting the issue to us.

Best regards,

Dear ESASky user,

The dotted lines indicate the direction of motion of the stars that have proper motion values in the Gaia DR3 catalogue. However, these dotted lines only change to the solid line when you zoom in enough to see the actual proper motion (or at least the position from epoch J2000 to J2016, the Gaia DR3 epoch). See these two screenshots as an example of zooming in on a star:

More information about this feature and the astrometric catalogues in ESASky can be found in the documentation here: https://www.cosmos.esa.int/web/esdc/esasky-interface#datapanel

I hope this answers your question and we hope you're finding ESASky useful.

Best regards,

Deborah

Dear Becky,

Thank you for your message. Please note that these outreach images are created by the HST mission for outreach purposes, and their astrometry will therefore sometimes not be as precise as Gaia. We will pass this information on to the Hubble Outreach team and see if there is anything that can be done to improve the astrometry of the images within ESASky. 

Kind regards,

Debbie, on behalf of the ESASky team
