##
## This script generate a series of regions for the extraction of
## radial surface brightness profile (SBP).
##
## Regions geneartion algorithm:
## (1) innermost 10 regions, we require a mininal of 5 pixel as well
## as 50 counts within the 0.7-7.0 keV range.
## (2) following regions: R_out = R_in * 1.2, and require STN > 1.5.
##
## Reference:
## [1] region generate algorithm ??? (TODO)
##
## Author: Zhenghao ZHU
## Created: ??? (TODO)
##
## ChangeLogs:
## v2.1, 2015/02/13, Weitian LI
## * added '1' to denominators when calculate STN to avoid division by zero
## * added script description
## v2.0, 2013/03/06, Weitian LI
## * added the parameter `-t' to print STN results for testing
