Science tables related to NuSTAR observations are available here. These are author-produced catalogs available through the HEASARC Browse and XAMIN services. Suggestions for additional tables useful to the NuSTAR community can be sent to HEASARC HelpDesk or email to antara.r.basu-zych [AT] nasa [DOT] gov.
Expert users who already know the Observation IDs (ObsIDs) of the dataset(s) in which they are interested, can also directly access NuSTAR data via the HEASARC's ftp site. The public NuSTAR data are at http://heasarc.gsfc.nasa.gov/FTP/nustar/data/obs/00/ in subdirectories 0, 1, 2, 3, etc., determined by the first digit of their ObsID: thus, the data for ObsID = 80001001002 are in the directory http://heasarc.gsfc.nasa.gov/FTP/nustar/data/obs/00/8/80001001002/.
There are some known 'issues' or unusual features for a number of the released datasets. Potentially problematical issues are indicated by the parameter issue_flag in the NUMASTER table having a value set to 1. The issue_flag may indicate a value of data_gap > 0, nupsdout > 0, solar_activity is not NULL, or use of a non-standard instrument setting. The specific nature of the issue affecting the observation will be indicated in one or more non-blank or non-zero values of the following parameters in NUMASTER: data_gap, nupsdout or solar_activity, or may be indicated in the comments field for the dataset. In addition, the coordinated parameter in NUMASTER lists observatories for which coordinated observations were made with the specified NuSTAR observation. The comments parameter in NUMASTER contains a brief text synopsis of the major known issues and unusual features.

Unanticipated ToO and DDT requests may be submitted through the NuSTAR SOC website. Note that the Principal Investigator of Guest Observer Programs may choose to waive the exclusive use period for their observations.
