Splinter session on Rosetta data in the EPSC-DPS meeting

By M. Taylor & D. Heather
Rosetta and 67P

The EPSC-DPS Joint Meeting is currently taking place in Geneva with several contributions by ESA planetary mission scientists and ESDC representatives. In particular, there will be a special splinter session related to Rosetta data on Tuesday, September 17.
The aim of the splinter session is to make the attendees familiar and as autonomous as possible with Rosetta archive data, so that they can quickly carry out their own cometary science studies. The target audience is cometary and small body scientists, as well as members of the broader planetary community, with the aim of making them aware of the data products available in the Rosetta archive, to promote usage of those data. The workshop will begin with a short presentation of the ESA Planetary Science Archive as a whole and on the Rosetta archive in particular. This will be followed by presentations from a few select instrument teams who will give a brief overview of their archive data, to provide instrument level insights into data access. Following this, we aim to have a more interactive section focusing on a published event, which will allow attendees to gain experience in interacting with the archive data.
All are welcome to attend.

Herschel-PACS spectrometer: Separate on-source and off-source cubes available

By I. Valtchanov, E. Verdugo & P. García Lario

Most PACS spectroscopy standard pipeline-generated products are background-subtracted. If one wished to compare the on-source to the off-source data separately, it would be necessary to re-process the data in HIPE. This has been done, and the resulting on-source and off-source cubes are provided as Highly Processed Data Products (HPDP) through the Herschel Science Archive.
For each observation, for each camera and each wavelength slice in the observation, one "equidistant mosaic cube" of the on-source pointing and one (for the unchopped mode) or two (for the chop-nod mode) cubes of the off-source pointings are provided.
In addition to the FITS files and the postcards for each observation, the scripts that were used to create these HPDPs are available in the Herschel legacy data repository area. These can be used to create alternative versions of the HPDP cubes, following the advice in the Release Note and in the related Technical Note, which explains what to do if you find "contamination" in your off-source data.

RUWE data now available in the Gaia archive

RUWE data in Gaia Archive

Since July 2019, following a decision made by the Gaia Data Processing and Analysis Consortium (DPAC) and ESA, an official release of the renormalised unit weight error (RUWE) data is available in the Gaia Archive along with the Gaia DR2 data. Up to now, this parameter, widely used to estimate the quality of Gaia astrometric measurements, had to be computed by users following the recipes given in the technical note GAIA-C3-TN-LU-LL-124-01, available from the Gaia documentation page. With RUWE available in the Gaia archive makes it easier for users to select objects with good quality astrometry. More details can be found from the Gaia DR2 known issues page.
Currently the RUWE data can be found as a separate table, but will be provided in the gaia_source table from the next Gaia data release (Gaia EDR3) onwards.


Latest data deliveries to the Planetary Science Archive

PSA data

The Mars Express mission continues its regular data deliveries to the Planetary Science Archive (PSA). Since mid-July, the following datasets have been added:

On the other hand, the Rosetta mission released a large batch of Rosetta RSI (Radio Science) gravity data covering the the period June 29 to September 29, 2016. With these deliveries, all gravity measurements from RSI for the full mission are now available in the PSA.


Last week to reply to the Astronomy User Survey

By D. Baines & B. López Martí

This is the last week to reply to our user survey! Have you not done it yet, we would be very grateful if you could spend a few minutes of your time filling it. The survey includes questions on the archives of EXOSAT, Gaia, Herschel, HST, ISO, Lisa Pathfinder, Planck, XMM-Newton and the ESASky tool. It should not take more than 5 minutes to complete.
Thank you very much for helping us in providing the Astronomy community with the best possible services from the ESA Astronomy science archives.
