"extra" subhalo and group catalog properties not implemented

[duncandc]

I have not yet implemented the "extra" properties for the subhalo and group catalogs. in Yu Fengs "readsubhalo.py" script there is an extradtype object defined. These should be investigated and incorporated into the dtype objects for the subhalo and group catalogs.

extradtype = numpy.dtype([
('type', 'u1'), # 0 for subhalo, 1 for contamination
('bhmassive', bhdtype), # properties of the most massive blackhole
('bhluminous', bhdtype), # properties of the most luminosous blackhole
('sfr', 'f4'), # total star formation rate
('bhmass', 'f4'), # total blackhole mass
('bhmdot', 'f4'),
('rmean200', 'f4'),
('mmean200', 'f4'),
('vdispmean200', 'f4'),
('rcrit200', 'f4'),
('mcrit200', 'f4'),
('vdispcrit200', 'f4'),
('mtoph200', 'f4'),
('rtoph200', 'f4'),
('vdisptoph200', 'f4'),
]) # total blackhole accretion rate
