PER  stricly periodic variable with sinusoidal light curve. This category may 
PER   include Delta Scuti, Beta Cephei, Slowly Pulsating B, Gamma Doradus and 
PER   other types of variability. However, we did not assign the type of 
PER   variability as this can be assigned in most cases only with additional 
PER   information like spectral type.
HADS high-amplitude Delta Scuti star.
RRAB RR Lyrae-type variable of Bailey type ab.
RRC  RR Lyrae-type variable of Bailey type c.
CEP  Cepheids, including also some RV Tauri-type variable candidates.
EW   Eclipsing binary with W UMa-type light curve.
EB   Eclipsing binary with Beta Lyrae-type light curve.
EA   Eclipsing binary with Algol-type light curve.
MIRA Mira-type variable.
QPER Star with a dominating periodicity, but showing also amplitude and/or phase
QPER  changes or periodic changes superimposed on the variability on a longer 
QPER  time scale. Stars of this type are commonly designated also as 
QPER  semi-regular (SR) or long-period variables (LPV).
APER star with no well-defined periodicity in light variations.
