M 35 graph fits

 

 

 

 

 

 

 

 

This observation know as M 35 is also on the younger side. It was chosen because it was easily visible and the HSC telescope was able to get nice picture of it. We got 22 different pictures and there were not many problems with stacking and aligning them. Then the pictures were grouped and colored and I think the pictures came out really good. The fit on the graph came out pretty good as well. The estimated age of M 35 was 100 million years. The actual age of M 35 is 110 million years old (Real data). This was a 10% margin of error.

M45 Data

For one of our younger open cluster we decided to choose the Pleiades since it is visible in the northern hemisphere and easy to spot. We set fifteen observations that for M45 that took various time lengths in their respective filters but made sure to do exposures in gprime, rprime, and uprime. Thereafter we archived stars in the image and stacked with the respective filters. Unfortunately, u prime did not want to work so data was restricted to just r and g prime. After it was stacked and stars were marked, we exported it as a csv file and plugged it into astromancer. In astromancer we cleaned up background stars as best we could but we think that several background stars still made it on the graph given that it does not follow it exactly. The line of best fit was adjusted as best we could and we got an estimated age of a 100(myr), which is accurate to the actual age of Pleiades which is between 90 and 115(myr).

Messier 92 graph fits

For an older observation we have M 92. This was chosen because it was easily visible and the PROMPT telescope was able to take it. 3 images were taken and were overlapped and colored. The images came out ok but I think if we got more pictures they would have come out clearer. The Fit on the graph above came out pretty well. I tried to fiddle with the bottom but this was the best I could get. The estimated age of this cluster is 13.4 billion years old. This was very cole to the real value which came out to 13.8 billion years old (Real data). This is only a 3% margin of error!
