ABSTRACT
We present a study of the electron density variation for
off limb observations with the Coronal Diagnostic Spec-
trometer (CDS) on board SoHO using the density sensi-
tive coronal line ratio Si X (356.0/347.4). The analysis
is divided into three parts: the latitudinal variation from
1.01
r/ 1.09, the temporal variation in successive
rasters, and the electron density along a hot coronal loop
found in one of the rasters.
Key words: CDS; SoHO; electron density; off limb; lati-
tudinal dependence; coronal loop.
1. INTRODUCTION
In the SoHO era, important efforts have been made to de-
termine the density, temperature and velocity above the
