glint

Calculate glint angle for TOMS/EP satellite using PySPICE

Usage:

Full-up script to create updated TOMS/EP HDF5 files:


    find TOMSEPL2/1996/07/ -name '*.he5' | grep -v '_glint\.he5$' | sort | xargs python tag.py


Prototype:

    python glint.py < glint.py

Uses NAIF/SPICE (PySPICE), h5py

Also needs two SPICE kernels:

Manifest

tag.py - Input TOMS/EP .he5 HDF5 files, calculate and append glint angle, write _glint.he5

glint_c.c - C version testing getelm_c/ev2lin_
glint_f.f - FORTRAN version  testing getelm/ev2lin

glint.py - prototype for tag.py

listfauxfile.py - support modules for tag.py
PDSImage.py     - support module for tag.py

Makefile - build glint_c and glint_f
