Dear Stuart,

 Thank you for your email.

 Having checked we found that there was an error in the RINEX header coordinates for ARIS, which we have only discovered upon receiving your email.

 The correct coords for ARIS are:

 3472288.7161     -355730.7490     5320460.9994

 Please note, ARIS has an antenna height of 0.1804 metres

 RINEX data for times/dates from now will be correct, we will either remove or correct the files already sent to the website.

 We are very sorry for any problems caused by this error and trust you will find this information to be helpful.
