All strips start at RA = 0° First strip (strip 0) is centered at Dec: 0° and covers from Dec: -01° to +01° All strips have a heigth of 2° (except the bins at the poles that cover from Dec: ±89° to ±90°). The number of bins per strip is: Strips 0 to ±2: 180 bins Strips ±3 to ±7: 175 bins Strips ±8 to ±12: 170 bins Strips ±13 to ±17: 155 bins Strips ±18 to ±22: 140 bins Strips ±23 to ±27: 115 bins Strips ±28 to ±32: 90 bins Strips ±33 to ±37: 60 bins Strips ±38 to ±42: 30 bins Strips ±43 to ±44: 5 bins Strips ±45: 1 bin
