# PSGRN and PSCMP (packaged as fomosto backend) |
|||
|
|||
Code to calculate synthetic stress/strain/tilt/gravitational fields on a |
|||
layered viscoelastic halfspace. |
|||
|
|||
PSGRN and PSCMP have been written by Rongjiang Wang. |
|||
|
|||
Packaging has been done by Hannes Vasyura-Bathke. |

# PARAMETERS FOR SOURCE-OBSERVATION CONFIGURATIONS |
|||
# ================================================ |
|||
# 1. the uniform depth of the observation points [km], switch for oceanic (0) |
|||
# or continental(1) earthquakes; |
|||
# 2. number of (horizontal) observation distances (> 1 and <= nrmax defined in |
|||
# psgglob.h), start and end distances [km], ratio (>= 1.0) between max. and |
|||
# min. sampling interval (1.0 for equidistant sampling); |

# |
|||
# r1,r2 = minimum and maximum horizontal source-observation |

# zs1,zs2 = minimum and maximum source depths (zs2 >= zs1 > 0). |

# |
|||
# Note that the same sampling rates dr_min and dzs will be used later by the |

# program "pscmp07a" for discretizing the finite source planes to a 2D grid |

# of point sources. |
