NuSTAR CALDB Update (16 Oct 2019)
The NuSTAR CALibration DataBase was updated on October 16, 2019 (CALDB version 20191008). This updates the NuSTAR clock correction file to version 96, valid through 2019-10-08.
NICER Stowed Due to ISS Operations (15 Oct 2019)
In support of ISS operations, NICER has been stowed since Sunday, October 13. As a result, NICER is not currently taking requests for Target of Opportunity observations. We anticipate that NICER observations will resume as soon as the ISS operations are completed.
NICER observations of the X-ray transient MAXI J1807+132: flaring activity (08 Oct 2019)
NICER has been monitoring the X-ray transient MAXI J1807+132 regularly since September 16. During this time, NICER detected brief, sudden episodes of X-ray brightening which may be analogous to similar flaring behavior seen near the end of the 2017 outburst of the source.
Fermi Science Tools Updated (07 Oct 2019)
The FermiTools (formerly the SAE) were updated to version 1.2.1 on October 4, 2019. This release contains a major update to the implementation of the energy dispersion correction method in the Fermitools. It also includes new tool called gtdrm that estimates the energy dispersion matrix for the energy binning, and fixes a bug which was preventing updated parameter files from installing.
M33 Supernova Remnant Catalog (M33SNRXMM) Catalog Released (02 Oct 2019)
The M 33 Supernova Remnant (SNR) catalog comprises of
deep observations of eight fields in M 33. This catalog includes 105
SNRs, detected at the 3-sigma level, of which 54 SNRs are newly
detected in X-rays, and three are newly discovered SNRs. This catalog
also includes optical emission line ratio data and results from X-ray
spectral fitting, based on deep Chandra survey data. This table is now available in Browse and
XAMIN updated (02 Oct 2019)
The HEASARC XAMIN archive interface has been updated to version 6.4. This release is a major update to installation utilities, along with other improvements.
