This directory contains the input files for 8 examples designed toillustrate all the important features of rayinvr, tramp, pltsyn and vmodel.The v.in, r.in, tx.in, s.in, d.in and vm.in files for the i'th example arecalled vi_s.in, ri.in, txi.in, si.in, di.in and vmi.in. For each examplethere are also ri_0.in and vi_0.in files which were used to create thesynthetic traveltime data (not applicable to examples 4, 6, 7 and 8). Thereis also an f.in file for the 7th examples (called f7.in). Script filescalled setupi are provided to setup the input files to start the i'thexample. The following table describes each example and the programs intended to be run for each (ri=rayinvr, tr=tramp, pl=pltsyn, vm=vmodel, dmp=dmplstsqr). For examples 1, 2, 3 and 5 it is instructive to run the 3 programs in succession for a few iterations to examine the convergence to the true models.Example   Description                                         Programs-------------------------------------------------------------------------   1      crustal example                                     vm,ri,dmp   2      refraction statics example using head waves         vm,ri,dmp   3      reflector example                                   vm,ri,dmp   4      synthetics for example 3                            tr,pl   5      refraction statics example using turning rays       vm,ri,dmp   6      synthetics for example 1                            tr,pl   7      real crustal data example with floating reflectors  vm,ri   8      s-waves (Sg) and conversions (PmS) for example 1    vm,ri,tr,pl
