v5 v6 21 21 Some more severe masking is seen below : 22 22 23 -'''masked areas''' 23 == '''masked areas''' == 24 24 25 25 the stacks have a lot of masked areas and … … 27 27 hidden (the 28 28 SN host galaxyin the green circle). 29 29 30 [[Image(stacks.png)]] 31 30 32 [[Image(stacks_2.png)]] 33 31 34 [[Image(stacks_3.png)]] 32 35 … … 35 38 on the highest pixel value, but are irregular shapes, sitting over 36 39 part of the psf. 40 37 41 [[Image(Stars_ppStack.png)]] 38 42 … … 44 48 with moderately bright stars. 45 49 46 -'''background''' 50 == '''background''' == 47 51 48 52 We are using the template 49 53 subtraction technique to remove the signal of the host galaxy. The SN residual on difference image is nice but it is 50 54 impossible to obtain an accurate measurement because of the background around the residual. 55 51 56 [[Image(SNres.png)]] 52 57 … … 54 59 two difference images obtained with the same procedure (right images from the LT (stacked with IRAF) left images from PS1 55 60 (stacked with IPP). 61 56 62 [[Image(SN2009kf.png)]] 63 57 64 We also found a bigger scatter between the zero points in the PS1 images 58 65 with respect the LT images. Here some numbers relative to the same
