I wrote something similar one week or so ago in a different thread ...
What question are you trying to answer here?
I can't even see to which post you are replying, neither formally nor
regarding the content. When you reply to a post, please quote the text
that you are referring to. For details e.g. see here:

My first question in this thread has already been answered by Derek.
Then I asked Rob two additional questions. He didn't reply until now,
however, I don't think that anyone else can answer the questions.
