- The unit of data: Length unit, like x, y z, is Re(the radius of the Earth). The unit of magnetic field data is nT. The unit of velocity is km/s. The unit of density is cm^-3. The unit of pressure is nPa. 1.'no2_bn_mp_betsuni_topo_halfopen_17_r0.dat ' contains the magnetic field and some plasma data on the surface of magnetopause in full time step(201 time steps) of case 2. This is a binary data, and you can read it as follows" read,ntht,nphi (ntht,nphi are integers) define xmp,ymp,zmp as the two dimension array (ntht,nphi) read,xmp,ymp,zmp (xmp,ymp,zmp is the coordinates of points, the unit is Re) define bn,bl,bm,p_1,b_mag,vx_1,d_1 (these are 2 dimensional arrays (ntht, nphi)) begin the loops for i=0,200 read,time(this is the time , you need to multiply 0.935 to get the physical time. For example, if the value of time you read is 680, then the physical time is 680*0.935) read, bn,bl,bm,p_1,b_mag,vx_1,d_1 (bn,bl,bm are the magnetic field data,p_1 is pressure, vx_1 is the magnitude of velocity,d_1 is the density) endfor 2. 'S05D07V750B0013-13bt_cut_large_bipolar_bt119 ' , 'S05D07V750B0013-13bt_cut_large_bipolar_bt120' and 'S05D07V750B0013-13bt_cut_large_bipolar_bt121' are the data in 3d of case2 in 119th(2225.3s),120th(2244s) and 121th(2262.7s) time step separately. These are binary data, you can read as follows: read,m,n,l (m,n,l are integers) define, x,y,z as 1 dimensional array, x(m), y(n), z(l) read,,x,y,z define d,vx,vy,vz,bx,by,bz,p,tracer as 3 dimensional arrays, like d(m,n,l). d is density, vx is the velocity of x axis, vy is the velocity of y direction, vz is the velocity of z axis, bx, by and bz are the magnetic field in x, y, z, p is pressure. tracer is the percentage of solar wind particles. read,d,vx,vy,vz,bx,by,bz,p,tracer 3.S05D07V750B0013-13bt_cut_large_bipolar_bt121.silo is a 3 dimensional data which can be opened and plotted by Visit. 4.no1_bn_mp_betsuni_topo_half_r0_178.dat and no3_bn_mp_betsuni_topo_half_1120_34.dat contains the magnetic field and some plasma data on the surface of magnetopause in only one time step of case 1 and case3. The time step of case1' s data is 178th, that is 3328.6s. The time step of case3' s data is 34th, that is 635.8s. These are binary data, you can read the data as follows: read,ntht,nphi ( these are integers) define xmp,ymp,zmp as 2 dimensional arrays, like xmp(ntht,nphi) read, xmp,ymp,zmp read, time( if you want to get the physical time point, you should calculate 0.935*time) define bn,bl,bm,p_1,b_mag,vx_1,d_1 as 2 dimensional arrays, like bn(ntht,nphi) read,bn,bl,bm,p_1,b_mag,vx_1,d_1 5. S05D48V300B0033-33bt_cut_large_bipolar37 , S05D07V750B0013-13bt_cut_large_bipolar_bt37 and S05D03V1200B0008-08bt_cut_large_bipolar_bt37 are the data in 3 dimension of case1 ,2 and 3 in the 37th(691.9s) time step separately. These data are the binary data and you can read these as the steps shown in 2.
