The following table describes the contents of the DRsup (Data Release Supplemental) imaging runs for DR7. the Key to the column headers is: Run: Run Rerun: Rerun Stpe: Stripe S: Strip (North or South or Overlap (1/2 way between N and S)) mu0: survey mu of the beginning of the run mu1: survey mu of the end of the run All run have nu limits of approximately -1.25 to 1.25 degrees. f0: First field archived (camcols 1-6 inclusive) nF: number of fields archived (camcols 1-6 inclusive) node: great circle ascending node (deg) incl: great circle inclination (deg) Comment: What does this point at on the sky, and what are the node and inclination in the great circle coordinate system of the stripe that this data is on. Using a mu between mu0 and mu1 and setting nu=0, one can determine the RA,DEC of these runs by converting from great circle coordinates using the formula of Stoughton et al. 2002 AJ 123, 485 as listed in section 3.2.2 (where 95 degrees is replaced by the 'node(stripe)' below throughout). whichDB: Where this data can be found runs CAS or DAS What: What this is imaging of: M31*: a scan over or near Andromeda (M31) Cross: a scan perpendicular to the regular SDSS stripe direction (for calib) Oblique: a scan at an angle to the SDSS stripe direction (for calib) PerPisc: a scan over the Per-Pisc Galaxy cluster region of sky MonX1,X2: a scan at an angle to the SEGUE const. Longitude stripes (for calib) S*test: a test scan of a SEGUE or Legacy stripe usually in cloudy conditions S*ts: a test scan of a SEGUE or Legacy stripe usually in cloudy conditions M71: a scan over the low-latitude globular M71 (run 6895 camcol 3 hits it) SGP: a scan on SEGUE stripe 90, later deprecated, near the South Galactic Pole ------------------------------------------------------------------------------- Run Re Stpe S mu0 mu1 f0 nF node incl whichDB What inDas ------------------------------------------------------------------------------- 2766 40 100 N 2.58 11.56 11 60 189.985 -90.002 runs Cross 0 3356 40 100 N 20.35 29.34 11 60 342.831 62.034 runs M31test 0 3366 20 100 N 21.77 40.19 14 124 342.870 62.000 dasonly M31 1 3367 20 100 S 21.26 40.27 11 128 342.870 62.000 dasonly M31 1 3511 40 100 N 93.61 100.34 31 45 245.195 -90.142 runs Cross 0 3512 40 100 N 63.07 74.89 11 79 335.415 25.315 runs Oblique 0 3557 40 100 N 88.17 99.26 11 74 65.497 89.961 runs Oblique 0 3559 40 100 N 62.58 73.80 11 75 335.411 25.305 runs Oblique 0 3610 40 61 N 25.19 45.10 15 133 95.000 -52.500 runs PerPisc 1 3628 40 61 S 24.88 46.14 24 142 95.000 -52.500 runs PerPisc 1 3629 40 61 N 28.45 46.12 11 118 95.000 -52.500 runs PerPisc 1 3634 40 62 N 24.20 45.16 22 140 95.000 -50.000 runs PerPisc 1 3643 20 62 S 28.98 45.29 11 110 95.000 -50.000 dasonly PerPisc 1 3643 40 62 S 28.98 45.30 11 109 95.000 -50.000 runs PerPisc 1 4334 40 205 N 49.05 92.76 11 292 32.000 35.000 runs SgrStrm 1 4448 40 100 N 76.50 89.68 11 88 263.018 -90.003 runs Cross 0 4516 40 205 N 123.76 150.40 11 178 32.000 35.000 runs SgrStrm 1 4629 40 100 N 261.25 304.81 11 291 64.995 -90.003 runs Cross 0 4822 40 291 N 295.38 378.78 11 557 325.100 50.810 runs MonX2 1 5064 40 90 S 341.01 370.35 22 196 95.000 20.000 runs SGP 1 5069 40 90 S 20.69 59.91 12 262 95.000 20.000 runs SGP 1 5070 40 90 S 44.82 49.61 11 32 95.000 20.000 runs SGP 1 5181 40 100 N 74.15 91.82 11 118 83.817 -90.002 runs Cross 0 5391 40 290 N 226.92 267.35 11 271 259.900 43.200 dasonly MonX1 1 5392 40 290 N 251.87 262.95 11 75 259.900 43.200 dasonly MonX1 1 5398 40 290 N 251.34 284.43 11 221 259.900 43.200 runs MonX1 1 5657 40 206 N 27.22 37.25 14 67 212.482 -90.001 runs Cross 1 5711 40 79 N 19.69 54.43 11 233 95.000 -7.500 dasonly S79Test 1 5867 40 17 N 119.94 154.97 11 235 95.000 17.500 dasonly S17test 1 5921 40 17 S 123.12 132.70 11 65 95.000 17.500 dasonly S17test 1 6073 40 213 S 81.26 91.44 11 68 263.808 89.997 runs Oblique 0 6168 40 1020 S 262.19 278.07 11 107 60.000 34.950 dasonly S1020Ts 1 6207 40 290 N 278.53 297.84 11 129 259.900 43.200 runs MonX1 1 6212 40 290 N 282.34 317.52 24 235 259.900 43.200 runs MonX1 1 6282 41 301 S 282.43 296.20 11 93 127.890 64.230 dasonly M71test 1 6426 40 293 S 23.33 41.15 11 119 344.670 60.100 runs M31halo 1 6469 40 72 N 38.30 57.17 11 127 95.000 -25.000 dasonly S72test 1 6470 40 72 N 46.28 52.87 11 45 95.000 -25.000 dasonly S72test 1 6481 40 1356 N 118.23 130.96 11 86 226.000 316.860 dasonly S1356ts 1 6751 40 205 N 194.28 217.34 11 154 32.000 35.000 runs SgrStrm 1 6782 40 100 N 205.82 232.62 11 180 32.000 35.000 dasonly SgrStrm 1 6794 41 205 N 216.15 249.09 11 220 32.000 35.000 runs SgrStrm 1 6895 40 100 N 285.33 291.02 42 39 127.890 64.230 dasonly M71col3 1 7185 40 1458 S 92.33 98.47 11 42 315.140 328.780 dasonly S1458ts 1 7210 40 100 N 20.28 40.49 11 136 344.670 60.100 dasonly M31halo 1 -----------------------------------------------------------------------------
