In order to test the success of the installation, one should run the test
script as outlined above. This proceeds as follows:
- runs synfast to produce the sky map file test.fits; compare this to map.fits
(supplied)
- runs map2gif to make the image test.gif; compare this to map.gif (supplied)
- runs smoothing to make test_sm.fits; compare this to map_sm.fits (supplied)
- runs map2gif to make the image test_sm.gif; compare this to map_sm.gif (supplied)
- runs ud_grade to degrade the map test.gif to
Nside = 4. The output is test_LOres.fits; compare this to
map_LOres.fits (supplied)
- runs map2gif to make the image test_LOres.gif; compare this to map_LOres.gif (supplied)
- runs hotspot to produce a map of the local extrema in test_LOres.gif. The outputs are test_ext.fits, test_min.asc and test_max.asc. Compare this to map_ext.fits, min.asc and max.asc (supplied)
- runs map2gif to make the image test_ext.gif; compare this to map_ext.gif
(supplied)
- runs anafast to compute the power spectrum of the sky map test.fits. The output is test_cl.fits; compare this to cl_out.fits (supplied)
The supplied files are present in the /Healpix_1.20/test directory, and this is
also where the results files are created.
In order to test the new HEALPix profile set-up one can then attempt
to run any F90 facility from any directory on your system. Similarly,
IDL should be tested by invoking hidl or hidlde.
