From: Alex Schmidt Date: Thu, 24 Oct 2013 11:35:46 +0000 (+0200) Subject: Ydalia: X-Git-Url: http://git.treefish.org/~alex/phys/proceedings_lattice13.git/commitdiff_plain/8e422e13d7ddcd89704668a0ccf688f2dfeea749?ds=inline Ydalia: Modified a little bit the text and the plots plaquettes.eps and segments.eps. The problem is that the blue and red links look the same in the printed version :-(. So I had to made the blue links fatter :-/ Also, I made the plots bigger since we have a couple of pages of extra space. --- diff --git a/pics/plaquettes-eps-converted-to.pdf b/pics/plaquettes-eps-converted-to.pdf index 2a823d9..118f100 100644 Binary files a/pics/plaquettes-eps-converted-to.pdf and b/pics/plaquettes-eps-converted-to.pdf differ diff --git a/pics/plaquettes.eps b/pics/plaquettes.eps index b8917d2..aada480 100644 --- a/pics/plaquettes.eps +++ b/pics/plaquettes.eps @@ -1,8 +1,8 @@ %!PS-Adobe-3.0 EPSF-3.0 %%Title: plaquettes.fig %%Creator: fig2dev Version 3.2 Patchlevel 5d -%%CreationDate: Tue Jul 9 14:10:29 2013 -%%BoundingBox: 0 0 719 108 +%%CreationDate: Thu Oct 24 13:01:56 2013 +%%BoundingBox: 0 0 721 108 %Magnification: 1.0000 %%EndComments %%BeginProlog @@ -81,7 +81,7 @@ end /pageheader { save -newpath 0 108 moveto 0 0 lineto 719 0 lineto 719 108 lineto closepath clip newpath +newpath 0 108 moveto 0 0 lineto 721 0 lineto 721 108 lineto closepath clip newpath -26.3 486.9 translate 1 -1 scale $F2psBegin @@ -126,38 +126,29 @@ n 1327 7300 m 1411 7209 l 1294 7250 l col0 s n 2025 7425 m 3075 6825 l gs col19 s gr % Polyline -n 3075 6825 m - 4500 6825 l gs col19 s gr -% Polyline - [90] 0 sd -n 3528 7429 m - 4503 6829 l gs col19 s gr [] 0 sd -% Polyline -7.500 slw -n 2325 7350 m 3075 6900 l 4275 6900 l 3525 7350 l - cp gs col11 1.00 shd ef gr gs col0 s gr -% Polyline -30.000 slw [120] 0 sd n 3525 7425 m 2025 7425 l gs col19 s gr [] 0 sd % Polyline -7.500 slw -gs clippath -3345 6988 m 3345 7140 l 3405 7140 l 3405 6988 l 3405 6988 l 3375 7108 l 3345 6988 l cp -eoclip -n 3375 6600 m - 3375 7125 l gs col0 s gr gr - -% arrowhead -n 3345 6988 m 3375 7108 l 3405 6988 l col0 s +n 6150 7425 m + 4650 7425 l gs col19 s gr % Polyline -30.000 slw [120] 0 sd -n 4650 7425 m - 5700 6825 l gs col19 s gr [] 0 sd +n 5700 6825 m + 7125 6825 l gs col19 s gr [] 0 sd +% Polyline +75.000 slw + [120] 0 sd +n 9900 7425 m + 10950 6825 l gs col9 s gr [] 0 sd % Polyline 7.500 slw +n 6000 6450 m + 6150 6450 l gs col0 s gr +% Polyline +n 8625 6450 m + 8775 6450 l gs col0 s gr +% Polyline n 4950 7350 m 5700 6900 l 6900 6900 l 6150 7350 l cp gs col11 1.00 shd ef gr gs col0 s gr % Polyline @@ -165,54 +156,86 @@ n 4950 7350 m 5700 6900 l 6900 6900 l 6150 7350 l n 6153 7429 m 7128 6829 l gs col19 s gr % Polyline -n 6150 7425 m - 4650 7425 l gs col19 s gr +7.500 slw +n 10200 7350 m 10950 6900 l 12150 6900 l 11400 7350 l + cp gs col11 1.00 shd ef gr gs col0 s gr % Polyline +75.000 slw [120] 0 sd -n 5700 6825 m - 7125 6825 l gs col19 s gr [] 0 sd -% Polyline -n 8325 6825 m - 9750 6825 l gs col9 s gr -% Polyline - [90] 0 sd -n 8778 7429 m - 9753 6829 l gs col9 s gr [] 0 sd +n 10950 6825 m + 12375 6825 l gs col9 s gr [] 0 sd % Polyline 7.500 slw -n 7575 7350 m 8325 6900 l 9525 6900 l 8775 7350 l +n 2325 7350 m 3075 6900 l 4275 6900 l 3525 7350 l cp gs col11 1.00 shd ef gr gs col0 s gr % Polyline 30.000 slw - [120] 0 sd -n 8775 7425 m - 7275 7425 l gs col9 s gr [] 0 sd + [90] 0 sd +n 3528 7429 m + 4503 6829 l gs col19 s gr [] 0 sd +% Polyline +n 3075 6825 m + 4500 6825 l gs col19 s gr % Polyline [120] 0 sd -n 9900 7425 m - 10950 6825 l gs col9 s gr [] 0 sd +n 4650 7425 m + 5700 6825 l gs col19 s gr [] 0 sd +% Polyline +75.000 slw + [210] 0 sd +n 7350 7425 m + 8775 7425 l gs col9 s gr [] 0 sd % Polyline 7.500 slw -n 10200 7350 m 10950 6900 l 12150 6900 l 11400 7350 l +n 7575 7350 m 8325 6900 l 9525 6900 l 8775 7350 l cp gs col11 1.00 shd ef gr gs col0 s gr % Polyline -30.000 slw -n 11400 7425 m - 9900 7425 l gs col9 s gr +75.000 slw + [90] 0 sd +n 8778 7429 m + 9753 6829 l gs col9 s gr [] 0 sd % Polyline - [120] 0 sd -n 10950 6825 m - 12375 6825 l gs col9 s gr [] 0 sd +n 9975 7425 m 11400 7425 l + 12375 6825 l gs col9 s gr +% Polyline +n 7320 7440 m + 8370 6800 l gs col9 s gr % Polyline +n 8350 6810 m + 9760 6810 l gs col9 s gr +/Symbol ff 283.33 scf sf +1500 7275 m +gs 1 -1 sc (n) col0 sh gr +/Symbol ff 283.33 scf sf +1650 8025 m +gs 1 -1 sc (n) col0 sh gr +/Symbol ff 200.00 scf sf +1650 7350 m +gs 1 -1 sc (2) col0 sh gr +/Symbol ff 200.00 scf sf +1800 8100 m +gs 1 -1 sc (1) col0 sh gr +/Times-Roman ff 233.33 scf sf +3300 6525 m +gs 1 -1 sc (+) col0 sh gr +/Times-Roman ff 233.33 scf sf +11175 6450 m +gs 1 -1 sc (+) col0 sh gr +% here ends figure;
