Thank you Roger.

I have looked at the maps Bruno has compiled, some of it is straightforward; some is a little obscure.

http://www.lesia.obspm.fr/perso/brun...T15h35m28s.jpg

In this map, I presume the large dot is where the occultation is complete (total extinction of the eclipsed star). What would the smaller dots on either side of this be? I would have presumed that an oval of appropriate major and minor radii would have represented the zone of the earth where the eclipse would be partial / total. The rectangular zone does not make sense to me (which is a sad indication of my levels of sense).

The last six parameters in the data set are not known to me.

C/A ?
P/A ?
vel is shadow transit velocity in km/sec I believe (reading from the README) although this might mean that the occultation would be over within milliseconds, which I intuitively think cannot be the case.
Delta ?
R* ?
K* ? These two parameters are stated in the readme as magnitudes in R* and K* (not V* and R*) but I am unacquainted with these terms. I presume they refer to particular wavelengths of light, but I don't know what they would be.
long ?

Thank you in advance for any information or links to appropriate pages.

Regards,
Tony Barry
