subject: China urban-rural anomaly series (latest version)
I have repeated the operations of yesterday. The new version (the rural
component of which is based on a max. of 39 series) of the urban minus
rural anomaly series is in your pigeon hole. I think that the urban
subset is unchanged from that used in the paper.
