 +The values of "PHASE CAL i/j INDEX" are as defined in the {{http://​www.haystack.mit.edu/​tech/​vlbi/​mark5/​vex.html | vex 1.5 standard}} **except**
 +
 +  * 0-based rather than 1-based
 +  * Only 0 and positive integers allowed.
 +  * They must come in numerical order
 +
 +Tone number 0 is defined as first tone above 0Hz in the recorded baseband.
