Synopsis
--------
**p2p_S1_TOPS_Frame.csh** *Master.SAFE Master.EOF Aligned.SAFE Aligned.EOF config.s1a.txt polarization parallel*

Description
-----------
**p2p_S1_TOPS_Frame.csh** A processing script for producing an interferogram from Sentinel-1 TOPS data.

Place the SAFE file in a directory called **raw** and a dem.grd file in a parallel directory called **topo**. 

Execute this command at the directory location above **raw** and **topo**.

During processing, F1, F2, F3 and merge folder will be generated. Final results will be placed in the merge folder, with phase.grd and corr.grd

The file dem.grd is a dem that completely covers the SAR frame, or is larger than the SAR frame. If the dem is omitted then an interferogram will still be created, but there will not be a geocoded output. A custom dem.grd file can be made at the website: http://topex.ucsd.edu/gmtsar

Required Arguments
------------------

*Master.SAFE*

	Full name of the master or reference SAFE file of the pair

*Master.EOF*

	Full name of the .EOF orbit file that matches the master or reference SAFE file

	One can download precise or restituted orbit files with :doc:`download_sentinel_orbits.csh` or :doc:`download_sentinel_orbits_linux.csh`
	
*Aligned.SAFE*

	Full name of the aligned or secondary SAFE file of the pair

*Aligned.EOF*

	Full name of the .EOF orbit file that matches the aligned or secondary SAFE file

	One can download precise or restituted orbit files with :doc:`download_sentinel_orbits.csh` or :doc:`download_sentinel_orbits_linux.csh`

*config.s1a.txt*

	The configuration file for interferogram processing. A default file can be generated using :doc:`pop_config.csh`

*polarization*

	Specify the polarization of the data you wish to process

	polarization  =  vv  vh  hh or hv

*parallel*

	Specify your processing mode (0) or (1). parallel =  0-sequential   1-parallel-running F1/F2/F3 simultaneously
