1651 Padron of Nochistlan. Where is it?

I have both of Sergio Gutierrez's books "Los Altos de Jalisco" Vol I & II. Vol I contains a census for Nochistlan in 1649 and Vol II has on for Nochistlan in 1664. At the end of Vol II there is a "Relacion o Descripcion del Curato de Nochistlan y Otros Pueblos, con su Padron [de 1651]" which seems to be a description of the people in the city.

Is the description above what is being considered as the Padron of 1651 or is there an actual census? If so, where can I access the census? Thank you
