 USAGE:
          queryMODEL_IR1(lat,lon)

 INPUT:
     lat                      latitude
                  
     lon                      longitude
                 
 OUTPUT: 
    output.txt    an ascii file that contains the information about the extracted model
    the format of the file "output.txt" is shown schematically below:


| MODEL.VS                                {This line describs the type of current model(shear wave velociry}       |
| CRUST0.5_IR1 (Movaghari and Javan 2020) {This line is a descriptive comment for the model}                       |
| Location lon.=50.00  lat.=35.00         {This line contains the location of the extracted 1-D model}             | 
|                                                                                                                  |
| DEPTH(KM){depth}    VS(KM/S){shear wave velocity}   STD(KM/S){standard deviation}                                |
|       ...                  ...                         ...                                                       |
