Reality Check
Penultimate Amazing
To be more exact Crawford's paper did analyze raw SN data but in such a way that he got the results that he wanted!SelfSim;12192368The recent CQ ATM thread '[URL="https://forum.cosmoquest.org/showthread.php?167525-Is-the-universe-static" said:Is the Universe Static?[/URL]' and Crawford's accompanying paper, at least demonstrated his willingness to put pen-to-paper, and perform analysis on what he thought was raw SN data. That he showed no particular affiliations with the EU nonsense, also raised the credibility of his arguments, thereby warranting more attention than EU ramblings, (IMO).
The A problem with the analysis of type Ia supernovae paper is an attempt to debunk the several papers that show that the widths of type 1a supernova light curves are time dilated as predicted in an expanding universe. These papers use standard techniques to take the raw data and calibrate the light curves. Crawford takes a template from the SALT2 model
That file is available at salt2_template_0.dat Average spectral sequence.SALT (for Spectral Adaptive Lightcurve Template) is a package for Type Ia Supernovae light curve fitting
Crawford's fatal error was to take raw SN data and fit it to that template, thus removing any possible trends! He plots width against redshift, gets a random looking scatter and declares the universe to be static. What he really has done is just show that the raw SN light curves vary from the template light curve.
David F. Crawford seems to have retired in 2003 and has spent his time writing about a static universe explained with his personal cosmology. No known association with EU, just yet another invalid tired light theory. ETA: An idea about cosmological redshift from "gravitational interactions" seems to stem from at least 1993.
