NICER Archive: Getting started

General

The NICER science data are organized by sequence (10 digit number), where a sequence corresponds to an observation of one day in lenght. The sequences are located in the HEASARC NICER data archive area in the /obs directory which is divided in one month interval subdirectories named YYYY_MM (YYYY year MM month). The sequences are located in the YYYY_MM. The archive structure is therefore:

 
                              /obs
 
         2017_06/  2017_07/  2017_08/  2017_09/    .....
