| Description |
English: I forgot how little of the cluster is actually covered by the WFC3 observations. I guess it's not so bad to have to crop off a lot of the ACS data (see here) because the lensed images are so distorted and skinny that it's hard to see them without looking very close.
Anyway, yeah, I think I am in love with the Frontier Fields project. There are three more fields going under the lens over the next year and a half with MACSJ0416.1-2403 coming up at the end of September. Oooh, that's actually pretty soon! (A total of 6 clusters will hopefully be done by 2016) I used the same technique for the noise this time as I did for the ACS data, which is to get rid of the color noise by placing a black layer on "color" mode over it with all of the bright points and galaxies masked off so that their colors are maintained.
