Note (1): Integer codes for the evolutionary class are used as alternative to
the string designation (see global note G1). First number (Code)
designates one of the detached, semi-detached or contact system. Second
and third numbers are used for subclass and additional information on
evolutionary class if known. Codes are defined as follows:
1 1 0 = Detached main sequence system
1 2 0 = Detached subgiant system
1 3 0 = Detached giant or supergiant system of unknown sub-class
1 3 1 = Detached system with early-type giants or supergiants
1 3 2 = Detached system with late-type giant or supergiant
1 4 0 = White dwarf system
1 5 0 = Symbiotic detached system
2 0 0 = Semi-detached system of unknown sub-class
2 1 0 = Classical algol
2 2 0 = Cool semi-detached system
2 3 0 = Hot semi-detached system
2 4 1 = Cataclysmic semi-detached system
2 4 2 = Massive X-ray semi-detached system
2 4 3 = Low mass X-ray semi-detached system
3 0 0 = Contact system of unknown sub-class
3 1 0 = Near-contact system of unknown sub-class
3 1 1 = Near-contact F system
3 1 2 = Near-contact V system
3 2 0 = Early-type contact system
3 3 0 = Late-type contact system of unknown sub-class
3 3 1 = Late-type contact A system
3 3 2 = Late-type contact W system
3 4 0 = Contact giant or supergiant system
Note (2): Integer codes for SpType are used for convenient data analysis. First
digit of both I3 B_SpCode1 and B_SpCode2 designates lower limit on SpType
(O,B,..etc.) of the primary and secondary spectra respectively as follows:
1 = O
2 = B
3 = A
4 = F
5 = G
6 = K
7 = M
0 = Last two digits designate spectral (subclass x 10).
For example SpType B1.5 is coded as 215, while F3 is coded as 430. We
use second sets of I3 number b_SpCode1 and b_SpCode2 for upper limit
on SpType of the primary and secondary if given. For example second
set of I3 codes is needed to encode SpType A8/F1 or B1-B2. For SpType
A8/F1 B_SpCode1 equals to 380 while b_SpCode1 equals to 410. If SpType
is unique then b_SpCode equals to 000. If only SpType without subclass
is given then B_SpCode and b_SpCode are lower and upper limit for
possible SpType. For example SpType F is encoded as 400 499.
Note (3): Float code for luminosity class is used for both primary and
secondary. First digit (before .) denotes lower limit for luminosity
class as follows:
1 = I
2 = II
3 = III
4 = IV
5 = V
6 = VI (sd, subdwarf)
7 = VII (WD, white dwarf)
The second digit (after .) designates upper limit for luminosity class.
For example luminosity class IV/V is coded as 4.5, while luminosity
class III is coded as 3.0.

Note (1): Class membership probability for the class N is the ratio of
classified systems of class N to the total number of classified
systems in the vicinity of a system in the parameter space. (3σ)
estimate is used as the size of this parameter space for each
observational value. In case of multiple classification the star was
considered to be classified successfully and was added to "catalog"
if CMP for one of the possible evolutionary classes was larger than
0.5. In this case alternative solutions (with CMP<0.5) are listed in
file "altern". The parameter given is (CMPx100)
