Halacha 1א׳

אִם תִּרְצֶה לֵידַע מְקוֹם הַשְּׁמֶשׁ הָאֲמִתִּי בְּכָל יוֹם שֶׁתִּרְצֶה. תּוֹצִיא תְּחִלָּה מְקוֹמָהּ הָאֶמְצָעִי לְאוֹתוֹ הַיּוֹם עַל הַדֶּרֶךְ שֶׁבֵּאַרְנוּ. וְתוֹצִיא מְקוֹם גֹּבַהּ הַשֶּׁמֶשׁ. וְתִגְרַע מְקוֹם גֹּבַהּ הַשֶּׁמֶשׁ מִמְּקוֹם הַשֶּׁמֶשׁ הָאֶמְצָעִי וְהַנִּשְׁאָר הוּא הַנִּקְרָא מַסְלוּל הַשֶּׁמֶשׁ:

If you want to know the true place of the sun on any day you want: First produce its average place for that day according to the way we have explained, and produce the place of the sun's apogee. [Then] subtract the place of the sun's apogee from the average place of the sun. And the remainder is what is called the path of the sun.

Halacha 2ב׳

וְתִרְאֶה כַּמָּה מַעֲלוֹת הוּא מַסְלוּל הַשֶּׁמֶשׁ. אִם הָיָה הַמַּסְלוּל פָּחוֹת מִק"פ מַעֲלוֹת. תִּגְרַע מְנַת הַמַּסְלוּל מִמְּקוֹם הַשֶּׁמֶשׁ הָאֶמְצָעִי. וְאִם הָיָה הַמַּסְלוּל יוֹתֵר עַל ק"פ מַעֲלוֹת עַד ש"ס תּוֹסִיף מְנַת הַמַּסְלוּל עַל מְקוֹם הַשֶּׁמֶשׁ הָאֶמְצָעִי. וּמַה שֶּׁיִּהְיֶה אַחַר שֶׁתּוֹסִיף עָלָיו אוֹ תִּגְרַע מִמֶּנּוּ הוּא הַמָּקוֹם הָאֲמִתִּי:

[Then] see how much is the path of the sun. If the path is less than one hundred and eighty degrees, remove the divergence of the path from the average place of the sun. But if the path is greater than one hundred and eighty degrees – up to three hundred and sixty degrees – add the divergence of the path to the average place of the sun. And that which there is after you add to it or subtract from it is its true place.

Halacha 3ג׳

וְדַע שֶׁאִם יִהְיֶה הַמַּסְלוּל ק"פ בְּשָׁוֶה אוֹ ש"ס בְּשָׁוֶה. אֵין לוֹ מָנָה אֶלָּא יִהְיֶה הַמָּקוֹם הָאֶמְצָעִי הוּא הַמָּקוֹם הָאֲמִתִּי:

And know that if the path is precisely one hundred and eighty or precisely three hundred and sixty, there is no divergence. Rather the average place is [also] the true place.
