+* Python2 (2.6 and higher; Python3 is NOT supported)
 * Sufficient computing power
  Note1: Standard unix system including Linux and Mac OSX is recommended. There has been reported that this code does not work properly on a Linux system mounted on a Windows drive. This codes are tested under Mac OSX 10.9.5 on 2.8GHz Quad-Core Intel Xeon machine and Fedora Core 20 on Intel Core i5-4690 3.50GHz machine. 
  Note2: Depending on the machine power, it takes <<several minutes>> if you run all the standard process. We recommend sufficient computing power at least similar to that we have tested. With our testing machine above, it takes about ~450 sec. (~200 sec. for noise calculation, ~155 sec. for emission line S/N calculation, and ~95 sec. for continuum S/N calculation).

 Some caution again:
 
 1. NOISE_REUSED option is only valid for the same condition (zenith angle, field angle, lunar condition, and exposure time). Please be careful when you use this option and DO NOT use the different values from those used when the noise file was created.
