# MaNGA fiducial metrology file # # Uses SDSS-style Yanny .par formatting # # The purpose of this file is to give fiducial positions relative to the center of an IFU # for fibers in a given bundle. This is used in the plate design stage where we need # to calculate magnitudes across a target galaxy but don't know which piece of hardware # will be used to observe it. Note that the fiber numbering scheme here is serpentine # and starts at the SW corner of the IFU, and that fnumDesign used here may therefore # not correspond identically to the arrangement of fnum in a real as-built bundle. # # The data structure is as follows. # # Data table entries: # 1) fnumDesign: Fiber number within the bundle with a serpentine mapping. # 2) raoff: The ra offset of the fiber in arcsec relative to the ifu center # 3) decoff: The dec offset of the fiber in arcsec relative to the ifu center # # raoff and decoff are both given in arcseconds, so they should be added to the central pointing to get # the effective on-sky coordinates of the fiber # E.g., if RA=213.3423D and DEC=52.3234D in decimal degrees (ALWAYS use double precision here!) # then RAfiber=RA+raoff/3600.D/cos(DEC*!DPI/180.) DECfiber=DEC+decoff/3600.D # # Assumes that outer fiberdiameter=2.5 arcsec, with plate scale 60 microns/arcsec typedef struct { int fnumdesign; float raoff; float decoff; } SIMBMAP; SIMBMAP 1 0.00000 0.00000 SIMBMAP 2 -1.25000 -2.16506 SIMBMAP 3 1.25000 -2.16506 SIMBMAP 4 2.50000 0.00000 SIMBMAP 5 1.25000 2.16506 SIMBMAP 6 -1.25000 2.16506 SIMBMAP 7 -2.50000 0.00000 SIMBMAP 8 -2.50000 -4.33013 SIMBMAP 9 0.00000 -4.33013 SIMBMAP 10 2.50000 -4.33013 SIMBMAP 11 3.75000 -2.16506 SIMBMAP 12 5.00000 0.00000 SIMBMAP 13 3.75000 2.16506 SIMBMAP 14 2.50000 4.33013 SIMBMAP 15 0.00000 4.33013 SIMBMAP 16 -2.50000 4.33013 SIMBMAP 17 -3.75000 2.16506 SIMBMAP 18 -5.00000 0.00000 SIMBMAP 19 -3.75000 -2.16506 SIMBMAP 20 -3.75000 -6.49519 SIMBMAP 21 -1.25000 -6.49519 SIMBMAP 22 1.25000 -6.49519 SIMBMAP 23 3.75000 -6.49519 SIMBMAP 24 5.00000 -4.33013 SIMBMAP 25 6.25000 -2.16506 SIMBMAP 26 7.50000 0.00000 SIMBMAP 27 6.25000 2.16506 SIMBMAP 28 5.00000 4.33013 SIMBMAP 29 3.75000 6.49519 SIMBMAP 30 1.25000 6.49519 SIMBMAP 31 -1.25000 6.49519 SIMBMAP 32 -3.75000 6.49519 SIMBMAP 33 -5.00000 4.33013 SIMBMAP 34 -6.25000 2.16506 SIMBMAP 35 -7.50000 0.00000 SIMBMAP 36 -6.25000 -2.16506 SIMBMAP 37 -5.00000 -4.33013 SIMBMAP 38 -5.00000 -8.66025 SIMBMAP 39 -2.50000 -8.66025 SIMBMAP 40 0.00000 -8.66025 SIMBMAP 41 2.50000 -8.66025 SIMBMAP 42 5.00000 -8.66025 SIMBMAP 43 6.25000 -6.49519 SIMBMAP 44 7.50000 -4.33013 SIMBMAP 45 8.75000 -2.16506 SIMBMAP 46 10.0000 0.00000 SIMBMAP 47 8.75000 2.16506 SIMBMAP 48 7.50000 4.33013 SIMBMAP 49 6.25000 6.49519 SIMBMAP 50 5.00000 8.66025 SIMBMAP 51 2.50000 8.66025 SIMBMAP 52 0.00000 8.66025 SIMBMAP 53 -2.50000 8.66025 SIMBMAP 54 -5.00000 8.66025 SIMBMAP 55 -6.25000 6.49519 SIMBMAP 56 -7.50000 4.33013 SIMBMAP 57 -8.75000 2.16506 SIMBMAP 58 -10.0000 0.00000 SIMBMAP 59 -8.75000 -2.16506 SIMBMAP 60 -7.50000 -4.33013 SIMBMAP 61 -6.25000 -6.49519 SIMBMAP 62 -6.25000 -10.8253 SIMBMAP 63 -3.75000 -10.8253 SIMBMAP 64 -1.25000 -10.8253 SIMBMAP 65 1.25000 -10.8253 SIMBMAP 66 3.75000 -10.8253 SIMBMAP 67 6.25000 -10.8253 SIMBMAP 68 7.50000 -8.66025 SIMBMAP 69 8.75000 -6.49519 SIMBMAP 70 10.0000 -4.33013 SIMBMAP 71 11.2500 -2.16506 SIMBMAP 72 12.5000 0.00000 SIMBMAP 73 11.2500 2.16506 SIMBMAP 74 10.0000 4.33013 SIMBMAP 75 8.75000 6.49519 SIMBMAP 76 7.50000 8.66025 SIMBMAP 77 6.25000 10.8253 SIMBMAP 78 3.75000 10.8253 SIMBMAP 79 1.25000 10.8253 SIMBMAP 80 -1.25000 10.8253 SIMBMAP 81 -3.75000 10.8253 SIMBMAP 82 -6.25000 10.8253 SIMBMAP 83 -7.50000 8.66025 SIMBMAP 84 -8.75000 6.49519 SIMBMAP 85 -10.0000 4.33013 SIMBMAP 86 -11.2500 2.16506 SIMBMAP 87 -12.5000 0.00000 SIMBMAP 88 -11.2500 -2.16506 SIMBMAP 89 -10.0000 -4.33013 SIMBMAP 90 -8.75000 -6.49519 SIMBMAP 91 -7.50000 -8.66025 SIMBMAP 92 -7.50000 -12.9904 SIMBMAP 93 -5.00000 -12.9904 SIMBMAP 94 -2.50000 -12.9904 SIMBMAP 95 0.00000 -12.9904 SIMBMAP 96 2.50000 -12.9904 SIMBMAP 97 5.00000 -12.9904 SIMBMAP 98 7.50000 -12.9904 SIMBMAP 99 8.75000 -10.8253 SIMBMAP 100 10.0000 -8.66025 SIMBMAP 101 11.2500 -6.49519 SIMBMAP 102 12.5000 -4.33013 SIMBMAP 103 13.7500 -2.16506 SIMBMAP 104 15.0000 0.00000 SIMBMAP 105 13.7500 2.16506 SIMBMAP 106 12.5000 4.33013 SIMBMAP 107 11.2500 6.49519 SIMBMAP 108 10.0000 8.66025 SIMBMAP 109 8.75000 10.8253 SIMBMAP 110 7.50000 12.9904 SIMBMAP 111 5.00000 12.9904 SIMBMAP 112 2.50000 12.9904 SIMBMAP 113 0.00000 12.9904 SIMBMAP 114 -2.50000 12.9904 SIMBMAP 115 -5.00000 12.9904 SIMBMAP 116 -7.50000 12.9904 SIMBMAP 117 -8.75000 10.8253 SIMBMAP 118 -10.0000 8.66025 SIMBMAP 119 -11.2500 6.49519 SIMBMAP 120 -12.5000 4.33013 SIMBMAP 121 -13.7500 2.16506 SIMBMAP 122 -15.0000 0.00000 SIMBMAP 123 -13.7500 -2.16506 SIMBMAP 124 -12.5000 -4.33013 SIMBMAP 125 -11.2500 -6.49519 SIMBMAP 126 -10.0000 -8.66025 SIMBMAP 127 -8.75000 -10.8253
