Well, that seems good. What kind of problems are you having?

After looking at your script, I can see that you have been bitten by a known
bug, that prevents to name a column with a name that contains another column
name as a substring. While I release a pytables version with a cure to this,
you may try the next column declaration that is free of this problem:

class ES(IsDescription):
    H1       =3D Int8Col(indexed=3D1)
    M1       =3D Int8Col(indexed=3D1)
    S1       =3D Int8Col(indexed=3D1)
    BS      =3D Int16Col(indexed=3D1)
    BP      =3D Float32Col(indexed=3D1)
    AP      =3D Float32Col(indexed=3D1)
    AS      =3D Int16Col(indexed=3D1)
    L1       =3D Float32Col(indexed=3D1)
    V1       =3D Int16Col(indexed=3D1)
    A1       =3D Int8Col(indexed=3D1)
    UD      =3D BoolCol(indexed=3D1)
    TV      =3D Int64Col(indexed=3D1)
    DT      =3D Float32Col(indexed=3D1)
    HI      =3D Float32Col(indexed=3D1)
    LO      =3D Float32Col(indexed=3D1)
