+ | * '''A local copy of the calibrated full-frame TESS FFIs'''. These files can directly be retrieved from MAST, using the link of http://archive.stsci.edu/tess/bulk_downloads/bulk_downloads_ffi-tp-lc-dv.html. Here, go for the section '''Full Frame Images''' and, within then, take look at '''Calibrated FFIs'''. There are the download scripts named <code>tesscurl_sector_1_ffic.sh</code>, <code>tesscurl_sector_2_ffic.sh</code>, ... one for each sector. | ||
+ | ** The simplest solution is to use these scripts directly to retrieve the files. Since these scripts retrieve just a bunch of files (without any particular directory tree), you may create some filesystem-level standard for the storage. A recommended directory tree can be <code>/pub/tess/ffi/cal/s1</code>, <code>/pub/tess/ffi/cal/s2</code>, ... for TESS Sectors 1, 2, ... respectively. | ||
+ | ** In each of these directories, there will be ~15500 ... ~20600 files. Each of these files has a size of 34 megabytes - therefore, in total, 520 ... 700 gigabytes for are needed for each directory. Up to Sector 12, the total volume is 7.6 terabytes. | ||
+ | ** These file-by-file retrieval <code>tesscurl_sector_*_ffic.sh</code> scripts are not so optimal in many sense. There might be a need of a day (20 ... 28 hours) to retrieve a single sector. However, you can speed up this process by using [[TESS:Efficient_download|these instructions]]. |
