41. Distance to the Crab Nebula
ID:
ivo://edu.euro-vo.org/tutorials/08_m1_distance
Title:
Distance to the Crab Nebula
Date:
02 Apr 2025 14:48:15
Publisher:
The GAVO DC team
Description:
Within this use case you learn about supernovae, exploding or exploded stars. In particular you will use information on the Crab Nebula (the 1054 aD supernova registered by Chinese astronomers) to derive its distance: an example of how some very important information may be gained from very simple arguments and geometry.

Title:
EUV-SYN
Short Name:
eit_syn.epn_core
Date:

Publisher:
IDOC
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.

50. Galileo EPD Calibrated Corrected Delta Event Data Collection

Title:
Galileo EPD Calibrated Corrected Delta Event Data Collection
Short Name:
EPD-DELTA-EVE
Date:
15 Dec 2022 19:26:15
Publisher:
Planetary Data System
Description:
These are reprocessed measurements by the Engergetic Particle Detector (EPD) instrument onboard the Galileo spacecraft that orbited Jupiter and measured intensities of ion and electron radiation in the keV and MeV energy range. This set is version 31 of reprocessing and version 1.0 of PDS delivery. The TOFxE and DeltaExE files include event data of ion measurements. Event data are different than the channelized data in the high, medium, and low resolution files. Event data record the full information of a measured particle. Every "event" is the measurement of a time of flight (TOF) within the instrument and energy deposited within a detector (TOFxE file), or two energy values deposited within the two detector layers (DeltaExE file). The deposited energy values are generally different from the energy the particle has in the ambient space. Event data provides measured values in the native resolution of the instrument. Because such high resolution increases data volume, event data cannot be taken continuously and downlinked all the time. Only the provided subset of this data was kept. The files are comma separated. Invalid entries will have values of -1.000000E+38. Times are provided in the format Year.DOYHHMMSSM (first column) and fractional year (second column) More information can be found in the User Guide. This file includes measurements by the EPD/CMS/DeltaExE instrument. For each counted event, the energy deposited in the two solid state detector layers (Ej_keV and Ek_keV columns) of the instrument are recorded.
