Figures for Use in Presentations 
Ω_{m}Ω_{Λ} 68%, 95%, and 99.7% constraints on Ω_{m} and Ω_{Λ } obtained from CMB (orange), BAO (green), and the Union Compilation (blue). Ω_{m}w 68%, 95%, and 99.7% constraints on Ω_{m} and w obtained from CMB (orange), BAO (green), and the Union Compilation (blue). Binned w 68% constraints on w(z) obtained from CMB, BAO, and the Union Compilation. w is constant over each bin. Note the poor constraints on w(z > 1). Binned ρ 68% constraints on ρ(z) obtained from CMB, BAO, and the Union Compilation. ρ is constant over each bin. Binned Hubble Diagram and Residuals Hubble Diagrams of Union Sample constructed with selection cuts and outlier rejection. Each sample is independently binned in redshift bins of 0.01. The xaxis is sqrt(redshift). Sample Construction The samples at a glance. Left to right:

Cosmology Tables Data to Perform Your Own Fits 
Union Compilation Magnitude vs. Redshift Table An ASCII table with tabseparated columns: Supernova Name, Redshift, Distance Modulus, and Distance Modulus Error. For Union2.1, there is an additional column for the probability that the supernova was hosted by a lowmass galaxy. Covariance Matrix A 580 by 580 (Union2.1) or 557 by 557 (Union2) or 307 by 307 (Union1) tabseparated ASCIIformat covariance matrix, available with or without systematics. Full Table of All SNe A latex table with columns: Supernova Name, Redshift, BBand Magnitude, Stretch, Color, Distance Modulus, Sample, Cuts Failed (if any). Note that the Union2 version of this table is unfortunately generated with a different script M than the Union2 redshift and distance table (SCPUnion2_mu_vs_z.txt). Note also that the 2002fx was present (rather than failing the lightcurve cuts) in an early version of the Union2.1 table. CosmoMC Code for Implementing Union Compilation Tar file containing the above tables with CosmoMC code for obtaining a cosmology likelihood. For the Union2.1 version of the code, we use the technique in Appendix C of Amanullah et al. (2010) for eliminating the marginalization over the absolute magnitude and delta.

Ω_{m}Ω_{Λ} and Ω_{m}w With and Without Systematics 68%, 95%, and 99.7% constraints from the Union Compilation. The filled contours show statistical constraints only; the dotted contours include systematic errors. w_{0}w_{a} 68%, 95%, and 99.7% constraints from the Union Compilation. The filled contours show statistical constraints only; the dotted contours include systematic errors. 
Lightcurve Data 
SCP HST Cluster Survey Supernova Photmetry Table containing the photometry of the SNe Ia from the survey. SCP Highz 01 Lightcurve Data and Filters Tar file containing lightcurve data for six distant supernovae, as well as the relevant bandpasses. Lightcurves are in SALT format. In most cases, the bandpasses are the complete system response. For the CFH12K and FORS1 bandpasses, some steps in the system are presented separately and must be multiplied by the filters. SNe Summary Table pdf version of the table containing discovery information and redshifts. Nearby 99 Lightcurves Tar file containing lightcurve data for the nine nearby SNe. Lightcurves are in SALT format. Nearby 99 Filters Tar file containing filter throughputs for each filter used with the nearby sample, as well as the "Standard" UVBRI filters. Perlmutter et al. (1999) Lightcurves Tar file containing lightcurve data for forty two SNe from Perlmutter et al. (1999). Lightcurves are in SALT format.
