To be precise, the text uses equal degrees (= ecliptical longitude), but Ben thinks that ascensions give better results. Also, if I understand him correctly, Ben directs the Asc of the revolution, but I believe 'Umar at-Tabari meant the profected Asc, making his technique a continuous monthly profection (to complement his continuous yearly profection).

Just a quick one but I am no genius at math. Eponymous Morinus software gives option for time including local apparent time. I seem to recall this in an issue to the man himself. When using the software offline I struggle to get it right when entering latitude and longitude of the place so I would appreciate any response but if it is simple to understand then gratitude

I'm not entirely sure what it is you are asking, but you should choose the time setting corresponding to whatever system was used in noting down the birth time. For modern births this would normally be a time zone, so you choose Zone and then the correct offset from GMT (+ for eastern longitudes, - for western), and Daylight saving where applicable. In Morin's own day, birth times would typically have been noted using local apparent time (where 12 noon is the time of the sun being on the MC), but whatever system of notation is used is just a matter of convention: if the sun is on the MC, it's on the MC, whether we call that time 12 noon or 1:08 PM.

It is a question of Time and age of time-keeping: before 1750 or after introduction of Standard Time.

The critical difference between local mean time and local apparent time is that the former keeps to a mean rate and the latter does not. The most obvious manifestation of this difference is that in local mean time reckoning, the clock usually has only an approximate relation to true noon, whereas by local apparent time reckoning, noon o'sun is always exactly noon o'clock. Local mean noon and local apparent noon coincide four times per year, yet local mean time severs the constant relationship between a clock and the Sun.

Thank you both - I set the software ages ago for the primary directions on an old computer that I have not used latelyand this is a feature where the default worked so I never noticed it before

Thanks to Margherita for the post about Morinus setup. I've been reading 'The Cycle of the Year' by Charles Obert and he has a page or two on setting up Morinus for primary directions, but makes no mention of choosing a directions key under PRIMARY KEYS or setting the PD-in-chart dialog with ecliptic-feet option. Forgive my ignorance not sure what the second setting does exactly. The primary keys setting does make sense.

The only thing with your page is that some of the settings don't show on the latest version of the traditional software.

But once again thank you for the info.

As you have already understood PRIMARY KEYS are needed to convert the direction arc in time. The same or almost the same arc with a different key (as Ptolemaic versus Placidian under the pole) give very different result.

PD in charts is something connected to PD charts. "From planets" means planets are taken with latitude (the under the pole and Regiomontanian ones), from their ecliptic feet no latitude (Ptolemy directions).
The other is something invented by the programmer, I don't know what is. In every case PD in charts settings is just for PD charts, not for the list.
