NEMO (Stellar Dynamics Toolbox)
NEMO (Not Everybody Must Observe) is a toolkit for stellar dynamics. At its core it manipulates an N-body system (snapshot), but can also derive or compute orbits, derive images and extract tables to take to other analysis systems.
== Architecture ==
NEMO was developed on Sun Workstations, but ports to most Unix like systems. At its core NEMO defines a series of objects (SnapShot, Orbit, Image) and associated header files and libraries to operate on them, and these mirror the data stored in a portable binary name and type tagged XML like format, dubbed ''structured file''. The program tsf in NEMO will show the contents of such a file in a human readable way. Another feature OF NEMO is that all its data can be piped from one task into the next, thus creating whole simulations in a simple Unix pipe. For example,
mkplummer - 1000 | snapscale - - vscale=0.5 | hackcode1 - - tstop=10 | snaptrim - - times=10 | snapgrid - - | ccdfits - final.fits
would create a 1000 particle Plummer sphere, scale the velocities down to below virial equilibrium, integrate this for 10 virial times to see it collapse, and take the particle distribution of the last snapshot and turn that into a FITS file to view in another astronomical analysis package.
