Who are the מאמ"ר and the כה"ח?

Question

I found a reference to turning the body when waving the lulav. The text reads

ויש נוהגים גם להפנות את הגוף לארבע רוחות (מאמ"ר יג; כה"ח צו).

What, please, is the meaning of the abbreviations used for the sources of this custom מאמ"ר יג; כה"ח צו and are the sources available online?

I found the reference at https://ph.yhb.org.il/13-05-04/ (at the bottom of the page).

Answer 1

The Ma'amar Mordechai can be found here.

The Kaf HaChayim can be found here.
