All last new events (e.g. new feature, new data, bug correction) in MP3C Services.

publication of the new web interface in production

New Web Interface open in production.

This is the complete released v2.0 version ready to go in production.


Ingestion of a new table

New table ingested in MP3C database.

New table release of asteroid masses which contains values that were obtained with different methods. In parallel the release of the "Search by: Best Values” tool, which can returns to the user our adopted value for each parameter and each asteroid, according to our choice (which is described in the paper by Delbo, Avedllidou and Morbdielli A&A 2019).

  • MASS: The masses (and uncertainties) for a set of 385 minor bodies

ANR Origins is starting

Starting date of the national French grant ANR "ORIGINS", which supports scientifically the MP3C. It aims to feed the database with new spectroscopic data and the new identification of asteroid families.

A new Web interface for MP3C

Release of a new Web interface for MP3C.

Following the release of MP3C v2.0 earlier this year, we have been working on its Web interface, to offer a clearer view on the different Services we propose.

Thanks to the help of the Gaia VO group at ARI, Heidelberg, we have entirely restructured the Web interface of MP3C, which we hope will help you in finding the service(s) that best suits your needs: the Search by Name, the Search by Properties, the TAP Services.


Release of MP3C 2.0

We are proud the announce the release of the second major version of MP3C. The entire database and engine have been rewritten, and the data have been updated. The Web interface has also been changed, to offer more services.

Starting from this version, we offer several access to the MP3C: for a single object, with Web forms, and also using VO TAP protocol. Results are all provided in VOTable.

We list here all the data sets included in MP3C, and complete details and bibliography are available in the Data & Statistics page.

  • Dynamical properties:
    • MPCORB: The IAU numbers and names of minor planets, and osculating orbital elements, from the Minor Planet Center.
    • AstDyS proper elements: The proper orbital elements from AstDyS.
    • AstDys families: The list of members for each dynamical family listed in AstDyS.
  • Surface properties:
    • PDS Taxonomy: The compilation of asteroids taxonomic classification from the PDS.
    • Absolute magnitudes and slope: The absolute magnitudes and slopes of asteroids in the HG, HG1G2, and HG12 systems, from Helsinki.
    • SDSS-based taxonomy: The taxonomic classes obtained by Carvano et al. (2010) from SDSS colours.
  • Physical properties:
    • TRIAD diameters: The albedo and diameter TRIAD compilation, from the PDS.
    • IRAS diameters:The albedo and diameter of asteroids obtained from IRAS mid-infrared photometry.
    • MSX diameters:The albedo and diameter of asteroids obtained from MSX mid-infrared photometry.
    • WISE diameters:The albedo and diameter of asteroids obtained from WISE mid-infrared photometry.
    • Stellar occultation diameters:The diameter of asteroids obtained from stellar occultations.
  • Observing data sets:
    • SDSS MOC: The SDSS Moving Object Catalog.

Cone Search Estimation

On the web page of the Cone Search Service, an estimation of the query result size (in sources and bytes) is now proposed when setting the cone parameters in the form.

The first number gives the maximum number of sources that can be returned by the Cone Search query. The second value is the estimated size of the resulting VOTable based on the maximum number of sources.

The color of the estimated size may change: orange for GiB, red for TiB and grey otherwise.

Besides, if the estimated size is bigger than the limit of the Cone Search service, then a red OVERFLOW label is displayed. Thus, you will know that if you run the Cone Search query, the result will probably be truncated. Then, you should probably choose a smaller radius or decrease the verbosity flag (i.e. the number of columns you want to get).


TAP examples with STILTS scripts

From the Gaia DR1, the ARI's TAP service has a special resource providing a list of query examples. This list is visible and usable in TOPCAT as described in the help page: "How to get ADQL examples in TOPCAT?" .

is developed together with a derived command line tool of the same author: STILTS . Thanks to this tool, you can easily reproduce queries, crossmatches, plots and anything you do in TOPCAT with just a single script file.

So, now, all examples provided by the TAP service are now associated with a STILTS script that you can download, and execute in order to easily and quickly reproduce the example and its figure(s). Do not hesitate to take inspiration from these scripts to fulfill your own use-cases.

TAP Examples


Gaia DR1 online!

The full Gaia DR1 is now available on ARI's Gaia Services.

On this website you can get all information about the content of this release. All of the eight tables are described in details on  Data & Statistics. In addition of a detailed textual description, you will find statistics and sky-maps for all numerical columns of all available tables.

To query these data, the ARI provides three services:

  • Single Source Search: to search on Gaia (or TGAS) a specific Gaia source or the closest Gaia source from a given position (or object name).
  •  Cone Search: to search all Gaia (or TGAS) sources around a given position with a given radius.
  •  TAP: for complex SQL-like queries. Crossmatch with any provided table or user's table(s) is also possible.

TAP Upload enabled in the Web interface

The TAP Web interface has now a new feature: the ability to upload one or several table when submitting an ADQL query.

However, there are some limitations you should be aware of:

  • The TAP protocol supports ONLY the VOTable format for uploaded tables. The Web form has then the same constraint.
  • When selecting a file, you will be asked a table name. This table name must start with a latin letter ({aA-zZ}) and may be followed only by an underscore (_), another latin letter ({aA-zZ}) or a digit ({0-9}).
  • There is no limit on the number of tables you can submit. However, you are limited on the size of the whole requests (2MB) and on the total number of rows (see the Capabilities of the TAP service).

Rehearsal Gaia data ready for testing

The rehearsal Gaia data for the first release are now accessible through the ARI's Gaia services. These data are simulated just for test purpose. Thus, you can see how services provided by ARI work and how you could use them for your own scientific purpose.
