Interface for a sPECtral Matrix ANalysis (iPECMAN)
The interface for data analysis aims at multi-dimensional measurements of planetary electromagnetic fields. It calculates characteristics of electromagnetic waves from in-situ spacecraft measurements. These characteristics are the key signatures of fundamental process in the solar wind and planetary magnetospheres. The interface is based on the PRASSADCO (PRopagation Analysis of STAFF-SA Data with COherency tests) analysis tool, developed originally in the frame of the ESA Cluster Project. PRASSADCO (link) is a tool designed to analyze multicomponent measurements of electromagnetic waves. It implements a number of methods used to estimate polarization and propagation parameters, such as
- the degree of polarization,
- sense of elliptic polarization and
- axes of polarization ellipse,
- the wave vector direction,
- the Poynting vector,
- the refractive index.
The above methods have been previously used and validated for analysis of data from the STAFF-SA instruments onboard the four Cluster spacecraft, the STAFF/DWP instrument onboard the Double Star TC-1 spacecraft, the LFEW instrument onboard the Double Star polar TC-2 spacecraft, the Cassini RPWS data, the IMSC and ICE instruments on the DEMETER spacecraft, the Polar PWI-HFWR data, and data from the EMFISIS Waves instrument onboard the NASA Van Allen Probes Spacecraft.
