The directory ~/www/noaa/cm85 contains the update through August 2017 of the previous data which covered through January 2015.

Here I do not reproduce the Scottish sceptic algorithm, so don't compute slopes of growing intervals, only MEM spectrum of both original and (Tonyb's) extended CET, backward to 1538 (CET original starts in 1659).
Tonyb's data available at http://curryja.file.wordpress.com/2011/12/long-slow-thaw-supplementary-information.pdf quoted in http://judithcurry.com/2015/02/19/the-intermittent-little-ice-age/

I also use the ETA (Mariani L., Zavatti F.: Multi-scale approach to Euro-Atlantic climatic cycles based on phenological time series, air temperatures and circulation indexes , Science of the Total Environment, 593-594, 253-262, 2017, doi:10.1016/j.scitotenv.2017.03.182) European Temperature Anomaly series which include CET series and its spectrum.

I'll try to connect these spectra with the results of the paper:
