    The following will hopefully link to reference 26:



    I have only just found this reference by Waldenand. Thank you very much for this. Perhaps this is why all seemed quiet 'on the Western Front' to me regarding irradiation as it is a definitive article.
    It is easy to loose articles as they come along in the listing.

    This paper would seem to be the final and definitive answer to the lunar/star issue of irradiation. It is particularly exciting to me, as it is the experimental method I used myself all those years ago, but in a highly refined and systematic fashion - done properly in other words.

    The conclusion is a maximum of 50 seconds of arc irradiation effect then at 900 ftLamberts, (the normal expected brightness of the Moon outside the Earth's atmosphere), with no effect noted for different stellar magnitudes.
    And 40 seconds of arc to be expected.

    The article concludes manual navigation is not accurate enough for Space navigation where accuracy to a few seconds of arc is required.

    A fascinating paper. Thank you again Waldendand.
