MaStar Special Stars

MaNGAID '53-1342755' (HD 37828)

For calibrating the line spread function (instrumental broadening kernel, LSF), we have observed one special plate which includes one star that belongs to many other stellar libraries. Star HD37828 is included in the ELODIE library, the MILES library, and the X-Shooter Spectral Library. This star has MaNGAID='53-1342755' and was observed on plate 9676 with IFUDESIGN 12704, using very short exposure times.

According to the 3D dust map and the Bailer-Jones distance estimates based on Gaia EDR3 data, this star has an estimated E(B-V) of 0.12 magnitude. MaStar spectra have not been corrected for foreground extinction. One needs to correct the spectrum for extinction before comparing it with other extinction-corrected spectrum of it or with theoretical models.

We have observed the following stars in common with the MILES Library. The table below shows the correspondence. They can be used for cross calibration.

In the MaStar project, we also obtained integral field observations of the cores of 8 globular clusters in the Milky Way: NGC4147, NGC5634, NGC6229, NGC6316, NGC6341, NGC6522, NGC6528, and NGC7078. These are observed using dithered observations like MaNGA. The targeting information and data are provided in the same format as MaNGA galaxy data. See this page for more details. For data access and data model, see the MaNGA data access page and the data model page.

We have targeted member stars of many open clusters and globular clusters as part of MaStar. These are very valuable for stellar parameter calibrations. At the moment, we do not have a comprehensive list of these targets. This may be provided in the future.
