## Column definitions

xyz (f8) - Cartesian coordinates of each galaxy in units of Mpc/h
id (u8) - unique object identifier
logsm (f8) - Base-10 logarithm of galaxy mass in units of Msun
logssfr (f8) - Base-10 logarithm of galaxy specific star formation rate in units of yr^-1
logsize (f8) - Base-10 logarithm of galaxy size in units of Mpc/h

## Column notes

* Nearly all values of xyz lie within the range 0 < xyz < 250
* The logsm column is a proxy for the total brightness of the galaxy
* The logssfr column is a proxy for galaxy color.
  - Smaller (more negative) values of logssfr should be redder.
  - Redness should saturate for values of logssfr at and below -11.
  - Blueness should saturate for values of logssfr at and above -9.5.
* The logsize column is a proxy for the size of each object
  - Typical values of logsize lie in the range -4 < logsize < -2
  - Note that object size is far smaller than box size.
