Update K1.interferometer

Hi @tathagata.ghosh, thanks for this! Is the reference in this file still correct, it currently says

# KAGRA at design sensitvity.
# https://arxiv.org/pdf/1102.5421.pdf
# WARNING: I think there's a typo in that reference for the orientation.

Hi @colm.talbot

I have overlooked the reference that have mentioned. I'll let you know after checking.

Thanks, Tathagata

Table 1 of https://arxiv.org/abs/1102.5421 gives the old values, but it is not an official KAGRA publication, therefore it makes sense to update it. @tathagata.ghosh what is the source of your numbers?

Here is the official document (https://gwdoc.icrr.u-tokyo.ac.jp/cgi-bin/DocDB/ShowDocument?docid=3824) for the location of the Kagra detector. I have transformed the physical distance to detector constants according to the BILBY convention. The updated values that I mention are also consistent with the LAL value (https://lscsoft.docs.ligo.org/lalsuite/lal/group___detector_constants.html).

However, I think we need to also check the current sensitivity of the Kagra detector.

Thanks @tathagata.ghosh, would you be able to update the comment to reflect that different reference?

Do you have a KAGRA design curve to hand that you would be able to put in this MR? Or would you rather leave that to a future contribution?

Compare with previous version

I have updated the references. I'm not sure about the current sensitivity. So, I prefer to leave it for future contribution.

Amazing, thanks @tathagata.ghosh!

My pleasure :-)
