NEAT - Nebular empirical analysis tool
neat (Nebular empirical analysis tool) is a code for calculating
chemical abundances from emission line spectra of photoionised
nebulae. It is designed to be very simple to use, returning robust
results with meaningful uncertainties. It was first described in
Wesson et al, 2012, and it has been used to determine abundances and
conditions for several samples of ionized nebulae (e.g. Stock et al,
2011, Westmoquette et al. 2013, Smith et al. 2014), and also as a
testbed for investigating uncertainties (Wesson et al, 2012).
None, binary is in /usr/local/bin
Version 1.8 was installed on Wednesday, 30 March 2016
It comes with test data:
requires a 2, 3 or 4 column ASCII file containing a list of emission
line fluxes. The file can contain two, three or four columns. If two
columns are found, the code assumes they contain the the laboratory
wavelength of the line (λ0) and its flux (F). Three columns are
assumed to be λ0, F, and the uncertainty on F (ΔF). Four columns are
assumed to be the observed wavelength of the line, λobs, λ0, F, and
ΔF. The rest wavelengths should correspond exactly to those listed in
the file utilities/complete_line_list. The flux column should be a
flux per unit wavelength (any units are fine), and the uncertainty on
the flux should be given in the same units. Examples can be found in
the example/ directory.

I changed /usr to /usr/local using
sed -i 's/usr/usr\/local/g' Makefile
then I did the same to all f95 files in ./source using
find . -name "*.f95" -print | xargs sed -i 's/usr/usr\/local/g'
I had to edit line 399 of filereading.f95, subroutine read_atomic_data(), to allow the filename variable to be 31 characters long instead of 25,
and installing to /usr/local worked.
