Convert to Profile ( code from ScriptListener )

Hi,

Does someone know with what does "swdM" (= "shadowMode" ) tally ?

var idconvertToProfile = stringIDToTypeID( "convertToProfile" );
    var desc1 = new ActionDescriptor();
    var idnull = charIDToTypeID( "null" );
        var ref1 = new ActionReference();
        var idDcmn = charIDToTypeID( "Dcmn" );
        var idOrdn = charIDToTypeID( "Ordn" );
        var idTrgt = charIDToTypeID( "Trgt" );
        ref1.putEnumerated( idDcmn, idOrdn, idTrgt );
    desc1.putReference( idnull, ref1 );
    var idT = charIDToTypeID( "T   " );
    desc1.putString( idT, """ProPhoto RGB""" );
    var idInte = charIDToTypeID( "Inte" );
    var idInte = charIDToTypeID( "Inte" );
    var idClrm = charIDToTypeID( "Clrm" );
    desc1.putEnumerated( idInte, idInte, idClrm );
    var idMpBl = charIDToTypeID( "MpBl" );
    desc1.putBoolean( idMpBl, true );
    var idsdwM = charIDToTypeID( "sdwM" );
    desc1.putInteger( idsdwM, 2 );
executeAction( idconvertToProfile, desc1, DialogModes.NO );
