Searchable Data with the DARTS Astro Query System

DARTS/Astro Query System has description of each data product in the database, so that you can easily and quickly search the data you want by sending a specific query to the database. In this page, we explain all the data products searchable within DARTS/Astro Query System. Also, we explain auxiliary database items which we added to the original tables.

Database items of each table for every satelite/project:

We are going to register all the available data under the DARTS Astrophysics category onto the DARTS/Astro Query System, so that all the DARTS Astro data are searchable.

Stored data products and tables

DARTS/Astro Query System maintain various data products explained in the following tables. Detail of each table is shown in the linked page from each table name. Also, please find the "Additional data items", which make all the tables handled consistently.

Additional auxiliary database items

Below, we explain the auxiliary database items in the DARTS/Astro Query System which have been added to the original information of the data products.

Items on the coordinates

Data products are usually maintenanced based on a single coordinate system. However, when you search data, it is more convenient if you can use any coordinates depending on your needs. Accordingly, in the DARTS/Astro Query System, we register the four coordinate values; equatorial coordinates (both J2000 and B1950), ecliptic coordinates and galactic coordinates. These database items are distinguished by suffixes to tell the coordinates:

  • Equatorial coordinate (J2000) ・・・ _ra, _dec
  • Equatorial coordinate (B1950) ・・・ _ra_b1950, _dec_b1950
  • Ecliptic coordinate ・・・ _ecliptic_longitude, _ecliptic_latitude
  • Galactic coordinate ・・・ _galactic_longitude, _galactic_latitude

For example, if a data product has the observation center coordinates, the database has all the following items:

  • Equatorial coordinate (J2000) ・・・ center_ra, center_dec
  • Equatorial coordinate (B1950) ・・・ center_ra_b1950, center_dec_b1950
  • Ecliptic coordinate ・・・ center_ecliptic_longitude, center_ecliptic_latitude
  • Galactic coordinate ・・・ center_galactic_longitude, center_galactic_latitude
Items on the date and time

Most of the data products have information related to the date and time, such as observation date, data processing completion date, data release date etc. Representation of date and time are not uniform in genral. In DARTS/Astro Query System, we use both UTC and MJD, the former does not have suffix, and the latter has the suffix "_mjd".

For example, for starting dates of observations, we prepare the items "observation_start_time" and "observation_start_time_mjd".

Items on the public data location

Using DARTS/Astro Query System, you can tell if the data you want exist in DARTS or not. If exist, we provide the "data_access_url" for the URL to download the data.
