MSG Registration Form


A quick question. I am completing the MSG User Registration Form.

I assume the Service Options are HRIT and LRIT Image Data Services.

The Data Frequency question ranges from quarter hourly to 6 hourly.
Checking the notes to the form implies there is a fee for all apart from
the 6 hourly. From reading the e-mails on this and other groups
reception seems to be more frequent than the 6 hourly.

What is the correct option and are the fees relevant.
