It appears that version distrib...   3325 2 By: valdes 10/25/2007 03:30AM Accessing the SLALIB routinesStarted by:FSBoyden, 10/12/2010 08:10AM Hi I want to correct some MJD values for light arrival - i.e. correct to Barycentre.

I have thought about importing the abs() command from linux but all comments say that it only works with int (I thought this was weird).
