|Important note for all data sets: Some particles may not exist at all times, but the tracking program has identified them as likely the same particle and thus with a continuous identity. However, it is known that occasionally the tracking program makes mistakes with this.|
The first six data sets were studied in:
Format of data: These are all textfiles with five columns. The columns are (x,y,z,t,ID). The (x,y,z) data are in microns. Each particle has a unique ID number assigned to it. Time t is an integer; to convert to seconds, multiply by the time step listed in the tables describing each data set.
The volume fraction is approximate, despite the three digits of accuracy listed for some of them. For the last four data sets, the volume fraction is between 0.58 and 0.63.
|time step||Comments||Figure usage|
|t20156q.txt.gz||0.459||10 s||(supercooled liquid; eventually crystallizes)||In the papers this is the phi=0.46 data set. Fig. 2 in Rodriguez Fris et al. 2011.|
|t19813q.txt.gz||0.517||18 s||(supercooled liquid; eventually crystallizes)||In the papers this is the phi=0.52 data set|
|t19823q.txt.gz||0.528||60 s||(supercooled liquid; eventually crystallizes)||This is the phi=0.53 data in the 2000 Science paper. With the benefit of hindsight, I think the reason the plateau in the MSD is higher for this experiment is likely that the noise floor is higher. See Poon, Weeks, and Royall for comments about this type of problem (Sec. 3.3.2 in particular).|
|t19603q.txt.gz||0.562||18 s||(supercooled liquid; eventually crystallizes)||phi = 0.56 data set used in many figures. Figs. 1,3,4 in Rodriguez Fris et al. 2011.|
|t19607i.txt.gz||0.596||120 s||(glass, after a long period of aging)||In the papers this is the phi=0.60 data set|
|t19615i.txt.gz||0.611||120 s||(glass, after a long period of aging)||In the papers this is the phi=0.61 data set|
|t19508i.txt in zip file||0.617||120 s||(glass, after a long period of aging)||This was only used in Weeks, Crocker, & Weitz 2007, as the phi=0.62 data set. The data were taken at the same time as the other data in the Science '00 paper.|
|t31108q.txt.gz||glass||20 s||stirred at t = -15 frames||Aging, but not used for figures|
|t31248b.txt.gz||glass||20 s||stirred at t = -10 frames||Primary data set for figures of Courtland & Weeks 2003|
|t31006.txt.gz||glass||20 s||stirred close to t=0 (plus or minus 10)||Aging, but not used for figures|
|t31306.txt.gz||glass||20 s||stirred close to t=0 (plus or minus 10)||Aging, but not used for figures|
The particle radius for all data sets is 1.18 microns.
The first six data sets are the ones used in our Science '00 paper on dynamical heterogeneities. The last four were used in our J Phys: Cond Mat '03 paper on aging. In particular t31248b.txt was the primary data set for the JPCM paper.
Format of data: These are all textfiles with two columns: [dt (s), dx^2 (microns^2]. These are the data shown in our 2002 Chem. Phys. paper, Fig. 1(a).
