IRAS Scheme Coordinate Designation
Designation by coordinates (IRAS scheme).
Observed magnitude at outburst.
Spectral region (p,j,v,r,i,B) of observed magnitude at outburst.
True maximum magnitude (based on extrapolation if deviating from observed magnitude at outburst).
Spectral region of true maximum magnitude.
'LL' for lower limit, otherwise blank.
Uncertainly flag (':').
Spectral region of minimum magnitude.
light curve type in the system of Duerbeck (PASP 93, 165 (1981)).
Time of Decline through 3 Magnitudes
Type of object.
NA = Fast nova, Time3-time smaller than 100 days, spectroscopically confirmed NB = Slow nova, Time3-time larger or equal than 100 days, spectroscopically confirmed NC = Extremely slow nova, typical time scale: decades N = Nova; light curve too poorly known to establish speed classThe following additions are used:
: = nova, not confirmed by spectroscopic observations ? = existence of object based on one photographic or a few independent visual observations ?? = existence based on no more than two visual observationsOther types of variability (objects once announced to be novae, but reclassified after more observations were obtained):
NR = Recurrent nova NL = Novalike variable (inhomogeneous group) UG = U Geminorum variable (dwarf nova) UGSS = U Geminorum variable, SS Cyg subclass UGSU = U Geminorum variable, SU UMa subclass UGZ = U Geminorum variable, Z Cam subclass UGWZ = U Geminorum variable, WZ Sge subclass (not yet official subclass) ZAND = Symbiotic variable (Z And type) XND = X-ray nova (transient) system consisting of a compact component and a dwarf or subgiant star with spectral type G to M M = Mira star (long-period variable of large amplitude) UV = UV Ceti type star (flare star) FU = FU Ori type star (pre-main sequence) SDOR = S Dor type star (Hubble-Sandage variable)
Year of outburst if known.
