| * Ross: has been building a catalog of 2015 data (along with 10 other stations from the region), found about 450 events in the second half of 2015 (Gary already did the first half). Used software to locate the events, using a cross-corr tool to study them. Some events are small and hard to identify, but trying to measure the phase velocity across the array. | * Ross: has been building a catalog of 2015 data (along with 10 other stations from the region), found about 450 events in the second half of 2015 (Gary already did the first half).

| * Gary: looking for things that could be located with regional data, so missing the very small events in the data. Otherwise there would be thousands of events that could be seen by the Homestake array that are not seen by regional stations. So these 450 events are some large explosions in mines and teleseisms. May have to backtrack and redo the first half of the year. | * Gary: looking for things that could be located with regional data, so missing the very small events in the data.

| - | + | * Vuk: How should we make this available? | |
| - | {{: | + | * Gary: could be made available easily right away. Making a large catalog to include all of the local events would take a long time and a lot of work. |
| + | * Gary: the catalog could be placed on the wiki, or we could put it in a repository and send the link to everyone. | ||
| + | * Vuk: we can do both, and keep a cleaned-up version on the wiki. | ||

| + | * Almost done with this first-order data analysis. Have data only to the nearest second, so made a code that looks at the cross correlations of data from the array to get the better timing. Needs to complete the last line of shots. Computed the timing corrections for each DUGL seismometer, | ||
