Hey Yuting!

So everything you're wanting should be relatively straightforward, given some forking and javascript work.

1. You can increase the redshift accuracy by increasing the binning of the templates/input spectra by increasing the arraySize here: https://github.com/Samreay/Marz/blob/gh-pages/js/config.js#L62
2. If you're looking at things in a lower redshift range, note that the startPower and endPower defined above the arraySize will determine the redshift range your xcors go to, so you could reduce the maximum wavelength if you're not needing higher redshift results.
3. You can scrap templates and add your own simpy by editing https://github.com/Samreay/Marz/blob/gh-pages/js/templates.js
4. In terms of redshift error, we found that usnig the width of the xcor peaks was not representative of the actual redshift error, and thats why its not used.
5. But... if you want to do it anyway, the each spectra class has the xcor data stored in templateResults: https://github.com/Samreay/Marz/blob/gh-pages/js/classes.js#L77, where each template result is a dictionary of redshifts, xcor values, and the template weight (https://github.com/Samreay/Marz/blob/gh-pages/js/workerMethods.js#L256)
