At the centre of the 'daisy' is the nearest bud to (-2, 0) [the very tip of the beak] that we've been able to 'see'. 2) MORE DETAILED DAISY BLC (-1.999 996 470 425 34, -0.000 000 000 096 21) Xtent 0.000 000 000 096 21 Maxits 1024 A different daisy this time (the first one is too tiny for our program to zoom in on). 3) ZOOMING IN TO THE CENTRE BLC (-1.999 996 470 354 98, -0.000 000 000 017 59) Xtent 0.000 000 000 035 77 Maxits 1024 4) OUR OLD FRIEND BLC (-1.999 996 470 342 54, -0.000 000 000 004 60) Xtent 0.000 000 000 010 27 Maxits 1024 Surrounded with a beautiful fringe of spindles. We produce our images on an AED512 graphics box; 512x512 pixels, 256 colours from a palette of 256^3. Here (if you can use it) is the colourmap that we use for displaying them (usually). It's organised as 256 lines of colour triples, each element in the range 0 .. 255. The triples are in R G B order. The first line (logical colour zero) specifies the black interior of the set. 0 0 0 254 0 1 253 0 2 252 0 3 251 0 4 250 0 5 249 0 6 248 0 7 247 0 8 255 255 255 250 250 255 245 245 255 240 240 255 235 235 255 230 230 255 225 225 255 220 220 255 215 215 255 210 210 255 205 205 255 200 200 255 195 195 255 190 190 255 185 185 255 180 180 255 175 175 255 170 170 255 165 165 255 160 160 255 155 155 255 150 150 255 145 145 255 140 140 255 135 135 255 130 130 255 125 125 255 120 120 255 115 115 255 110 110 255 105 105 255 100 100 255 95 95 255 90 90 255 85 85 255 80 80 255 75 75 255 70 70 255 65 65 255 60 60 255 55 55 255 50 50 255 45 45 255 40 40 255 35 35 255 30 30 255 25 25 255 20 20 255 15 15 255 10 10 255 5 5 255 0 0 255 255 0 0 255 20 0 255 40 0 255 60 0 255 80 0 255 100 0 255 120 0 255 140 0 255 160 0 255 180 0 255 200 0 255 220 0 255 240 0 255 255 0 255 255 5 255 255 10 255 255 15 255 255 20 255 255 25 255 255 30 255 255 35 255 255 40 255 255 45 255 255 50 255 255 55 255 255 60 255 255 65 255 255 70 255 255 75 255 255 80 255 255 85 255 255 90 255 255 95 255 255 100 255 255 105 255 255 110 255 255 115 255 255 120 255 255 125 255 255 130 250 255 130 245 255 130 240 255 130 235 255 130 230 255 130 225 255 130 220 255 130 215 255 130 210 255 130 205 255 130 200 255 130 195 255 130 190 255 130 185 255 130 180 255 130 175 255 130 170 255 130 165 255 130 150 255 130 145 255 130 140 255 130 135 255 130 130 255 130 125 255 130 120 255 130 115 255 130 110 255 130 105 255 130 100 255 130 95 255 130 90 255 130 85 255 130 80 255 130 75 255 130 70 255 130 65 255 130 60 255 130 55 255 130 50 255 130 45 255 130 40 255 130 35 255 130 30 255 130 25 255 130 20 255 130 15 255 130 10 255 130 5 255 130 0 255 130 0 255 125 0 255 120 0 255 115 0 255 110 0 255 105 0 255 100 0 255 95 0 255 90 0 255 85 0 255 80 0 255 75 0 255 70 0 255 65 0 255 60 0 255 55 0 255 50 0 255 45 0 255 40 0 255 35 0 255 30 0 255 25 0 255 20 0 255 15 0 255 10 0 255 5 0 255 0 251 0 4 250 0 5 249 0 6 248 0 7 247 0 8 246 0 9 245 0 10 244 0 11 243 0 12 242 0 13 241 0 14 240 0 15 239 0 16 238 0 17 237 0 18 236 0 19 235 0 20 234 0 21 233 0 22 232 0 23 231 0 24 230 0 25 229 0 26 228 0 27 227 0 28 226 0 29 225 0 30 224 0 31 223 0 32 222 0 33 221 0 34 220 0 35 219 0 36 218 0 37 217 0 38 216 0 39 215 0 40 214 0 41 213 0 42 212 0 43 211 0 44 210 0 45 209 0 46 208 0 47 207 0 48 206 0 49 205 0 50 204 0 51 203 0 52 202 0 53 201 0 54 200 0 55 199 0 56 198 0 57 197 0 58 196 0 59 195 0 60 194 0 61 193 0 62 192 0 63 191 0 64 190 0 65 189 0 66 188 0 67 187 0 68 186 0 69 185 0 70 184 0 71 183 0 72 182 0 73 181 0 74 180 0 75 179 0 76 178 0 77 177 0 78 176 0 79 175 0 80 174 0 81 173 0 82 172 0 83 Enjoy...
