Next: Observatory table Up: Star tables Previous: Multiple star files . Some standard-star files are supplied for the UBVRI and uvby-H-Beta systems. ... You can also make new tables of standard stars. The easiest way to make standard-star tables is to begin as though they were program-star tables, but to include columns of standard values in the ASCII file, and field descriptions for them in the format file, before running MAKE/STARTABLE . ...

... The absolute flux calibration of NICMOS will be calculated from observations of standard stars with known flux distributions F( ). ... In order to expand the set of IR standard stars in the appropriate flux range for NICMOS, M. Rieke, R. Thompson, and collaborators at the University of Arizona are making photometric observations of solar-analog stars, which will be used to normalize the solar spectrum to the observed IR magnitudes. ... Relative flux references accurate to 1.5% for standard...

... A Hubble diagram for Quasars . ... The potential use of such relation as a cosmological probe is obvious: assuming no redshift evolution of the relation, the observed X-ray flux is a function of the observed UV flux, the redshift, and the parameters of the adopted cosmological model. ... In this framework, Guido Risaliti and Elisabeta Lusso (INAF-Arcetri Observatory) have recently published in the Astropysical Journal the first Hubble Diagram for quasars suitable for cosmological measurements . ...

... Optical photometric data were taken of fields encompassing all these sources during a total of seven telescope runs. ... The initial goal of the photometric observations is to follow up the X--ray sources, assign them colors in a standard system, so that the observed objects can be placed on a color--magnitude diagram. This can be used to verify that the X--ray sources are indeed PMS stars. ... Aperture photometry was performed using the APPHOT package in IRAF. ...
