\caption{This table details the information relevant to each individual galaxy surveyed. The central wavelengths of all filters used as well as the camera with which the image was taken motivated the choice of cluster detection method, where the presence of more than two different cameras in the sample led to difficulties in white light image creation. The source detection threshold in sigma above the background is included, as well as the distance modulus of the galaxy and the calculated minimum detectable mass of a cluster in that galaxy.}
\end{table}\subsection{Source detection}
All images examined were from the Hubble Space Telescope's MAST archive, using different filters and cameras for each galaxy depending upon availability of data; Filter and camera choice for each galaxy is shown in Table 1. On these images, two point source detection methods were used: The primary method used was the "white light" detection method as in (KAVIRAJ 2012). The other method was to compile separate source catalogs for the F555W filter and the filter closest to F336W using the PYRAF command DAOFIND and take the overlapping sources as the output catalog. This Cross-comparison method was used whenever the galaxy had a combination of too many different cameras and low source counts leading to an unusable white light image.
% Caption is not showing up? According to: https://www.authorea.com/issues/432 I should be able to tweak this in the settings, but the tree under settings doesn't really resemble what the commenter described.
% should I go into more detail on the white light method too?
