<p class="MsoNormal"><span lang="EN-GB">Quick
question concerning the magnetic declination.</span></p><p class="MsoNormal">How you indicate
it?</p>
<p class="MsoNormal"><span lang="EN-GB">Just by entering
the date or with the command <declination>?</span></p>
<p class="MsoNormal"><span lang="EN-GB">Because when
I just specify the date, the declination which is calculate is for the first January,
even if I specify another month in the centreline (e.g. 28.08.2017). Consequently,
centreline is slightly offset that if I enter the real declination for the date.</span></p>
<p class="MsoNormal"><span lang="EN-GB">I don’t
know if this shift is important for survey accuracy or if I can ignore it ?</span></p>
<p class="MsoNormal"><span lang="EN-GB"> </span></p>
<p class="MsoNormal"><span lang="EN-GB">Thanks and
sorry for all my questions.</span></p>
