Table information for 'eit_syn.epn_core'

General

This table is available for ADQL queries and through the TAP endpoint.

Resource Description: *** EUV-SYN *** Synchronous synoptic maps of the corona in the extreme-UV (EUV), built from series of SoHO/EIT observations, in each of the 4 wavelength bands of the instrument. Synchronous synoptic maps are maps of the EUV radiance in different wavelength bands on the full solar sphere, in heliographic (Carrington) longitude and latitude, where data are taken as close as possible to a reference time. They capture the state of the corona at any given reference time by including data taken as close as possible to this time. EUV-SYN is available as part of the generic MEDOC interface which is currently located at https://idoc-medoc.ias.u-psud.fr/. These interfaces are based on the CNES SiTools2 framework. EUV-SYN is also available from IDL and Python scripts, using a specialization of the generic SiTools2 IDL and Python clients developed by MEDOC.
