Boud Roukema de3d89c954 Disambiguate radial vs tangential distances; other fixes 
Changes in this commit include:

* Remove inconsistent usage of 'r', so that now it always represents
the spatial geodesic (comoving) distance; r_\perp is now used for
the comoving length of an arc of one radian (area-l distance), so
that the orthographic form of the line element is geometrically clearer.

* Fix 2-point autocorrelation function definition.

* other minor fixes in cosmology.tex

* replace non-free Georges Lemaitre image by free-licensed one

* improvements in Cosmology.mk makefile rules

* warnings and hints about the Imagemagick security policy

* 2-second delay between downloads in download*.sh scripts

Presentation pdf for 30-hour course in cosmology. All materials are fully free-licensed. See the download URLs for details of individual figures, some of which have more permissive conditions than the default CC-BY-SA-4.0 licence.

You should be able to create the pdf with make -f Cosmology.mk, although you may have to install some standard packages such as:

  • fig2dev (e.g. the package could be called fig2dev or fig2ps)
  • ghostscript
  • imagemagick
  • texlive-latex-base
  • texlive-latex-extra
  • texlive-latex-recommended
  • xfig e.g. in a Debian GNU/Linux or Debian derivative system such as Ubuntu, do
sudo aptitude install fig2dev ghostscript imagemagick \
  texlive-latex-base texlive-latex-extra texlive-latex-recommended xfig

Imagemagick security policy:

You will quite likely have to temporarily modify your imagemagick security policy, which will need sudo (root) access. Type convert -list policy to find your current policy, and temporarily add necessary permissions if needed. See https://imagemagick.org/script/security-policy.php for details. Remember to restore your original security policy afterwards.
