Add spacecraft location and instrument pointing coordinates to returned data #1
Description
The original CDF files (at least HET level 2) contain spacecraft location coordinates (R, heliocentric latitude & longitude), these should be contained in the returned data. In addition the pointing direction of the instrument is given as (time-independent?) variable XYZ, which will be very useful for calculation pitch-angles.
