variability type description

variability type description
LB Slow irregular variables. The light variations of these stars show no evidence of periodicity, or any periodicity present is very poorly defined and appears only occasionally. Like for the type I, stars are often attributed to this type because of being insufficiently studied.
Many type L variables are really semiregulars or belong to other types.

LB
Slow irregular variables of late spectral types (K, M, C, S); as a rule, they are giants (CO Cyg). This type is also ascribed, in the GCVS, to slow red irregular variables in the case of unknown spectral types and luminosities.

LC
Irregular variable supergiants of late spectral types having amplitudes of about 1 mag in V (TZ Cas).
