NRS = not resolved from other parts of SNR
INC = incomplete data, much of SNR not observed
NRB = not resolved from nearby bright sources
ND = no data, not observed
S = shell
F = filled center, plerionic
IR = irregular
CO = central object
NI = neutron star, isolated
NB = neutron star in binary system
(1) = rates corrected to 1 Jan. 1979.
(2) = estimated from partial HRI observation and HRI/IPC
ratio.
(3) = includes surrounding diffuse emission.
