+This script applies a tropospheric correction to unw data using GACOS data. GACOS data may be automatically downloaded from COMET-LiCS web at step01 (if available), or could be externally obtained by requesting on a GACOS web (http://www.gacos.net/).
 If you request the GACOS data through the GACOS web, the dates and time of interest can be found in baselines and slc.mli.par, respectively. These are also available on the COMET-LiCS web portal. Once the GACOS data are ready, download the tar.gz, uncompress it, and put into GACOS dir. 
 Existing files are not re-created to save time, i.e., only the newly available data will be processed. The impact of the correction can be visually checked by showing GACOS_info.png and */*.gacos.png. This step is optional.
