Bases: DatabaseEntryType, Base

This represents the main table of the database and each instance represents one record that can be saved in the database.

Parameters:

  • id (int) – A unique ID number. By default it is None, but automatically set to the maximum number plus one when this entry is added to the database.

  • source (str) – The source is the name of an observatory or the name of a network of observatories.

  • provider (str) – The name of the server which provides the retrieved data.

  • physobs (str) – A physical observable identifier used by VSO.

  • fileid (str) – The file ID is a string defined by the data provider that should point to a specific data product. The association of fileid to the specific data may change sometime, if the fileid always points to the latest calibrated data.

  • observation_time_start (datetime.datetime) – The date and time when the observation of the data started.

  • observation_time_end (datetime.datetime) – The date and time when the observation of the data ended.

  • instrument (str) – The instrument which was used to observe the data.

  • size (float) – The size of the data in kilobytes.

  • wavemin (float) – The value of the measured wave length.

  • wavemax (float) – This is the same value as wavemin. The value is stored twice, because each sunpy.net.dataretriever.client.QueryResponse which is used by the vso package contains both these values.

  • hdu_index (int) – This value provides a list of all available HDUs and in what files they are located.

  • path (str) – A local file path where the according FITS file is saved.

  • download_time (datetime.datetime) – The date and time when the files connected to a query have been downloaded. Note: this is not the date and time when this entry has been added to a database!

  • starred (bool) – Entries can be starred to mark them. By default, this value is False.

  • fits_header_entries (list) – A list of FitsHeaderEntry instances.

  • tags (list) – A list of Tag instances. Use sunpy.database.Database.tag to add a new tag or multiple tags to a specific entry.
