Description

The specification for the flag (provided by Embassy of Mauritania in Tokyo, Japan) gives the hoist as a 20/60/20 for the red/green/red areas. In the green section, the crescent and star take 67% percent of that space (20/10/40/10/20 according to the sheet). The other interesting thing is that the tip of the crescent horns end where the star arms meet at their outermost points. The flag maintains the 2x3 overall ratio.

There are also assigned colors; green is Pantone 354 Uncoated, Yellow as Pantone Yellow 012 Coated and Red as 18.1664. I believe the red shade is an error as Pantone does not have partial values; my guess is 186 Coated.

Everything except 20-10-40-10-20 and 75-75 are speculations based on the drawing provided in the specifications. The star seems to be set in a circle with radius 10 its bottom being in the centre of the flag (crossing point of the diagonals), thus its centre 10 units toward the top of the centre of the flag.
The horizontal line of the regular star inscribed in it (being approximately 13 units upwards from the horizontal median of the flag) seems to be also the line in which the horns of the crescent end.
The crescent itself seems to have been constructed not from regular circles, but ellipses, the lower edge being an ellipse with the centre in the above-mentioned horizontal line ca. 13 units up from the median, with axes being 74 and 66 (horizontal and vertical respectively). The upper edge is in an ellipse with the centre at the edge between the red and green fields, thus 30 units above the median, with axes 82 and 80. This makes the crescent at its widest 10 units wide.

Now, it may well happen that this speculation is not worth much, as the drawing we got may have been distorted in scanning and other procedures it went through, or it may simply be not precise drawing enough in those details, but this is best we have so far.
