RD curves produced by rd_collect.sh and AreWeCompressedYet are text files with one data point per line, separated by spaces.

The file headers are:

 <-v quantizer value> <number of pixels per clip> <file size in bytes> <PSNR> <PSNR-HVS> <SSim> <FastSSim>

The units for all the metric results are in dB.
See the tools directory in the Daala source code for how they are calculated.
