SNLS Type Ia SN Rate: Rate Gradient with Redshift



Redshift binning

We binned our sample by redshift into 0.2 to 0.4 and 0.4 to 0.6:


            0.2 - 0.4     0.4 - 0.6
Field          (N)           (N)       years
D1              4            11          2
D2              6            11          2
D3              5             3          1
D4              3             8          2

Here are the resulting volumetric rates for the two bins and the entire survey range for comparison:

0.2 - 0.4         0.27 +- 0.07
0.4 - 0.6         0.51 +- 0.09

0.2 - 0.6         0.44 +- 0.07
