| 内容記述 | The faint (1.8 micro Jy, 2-11 keV) X-ray QSO 4U0241+61 is considered in terms of its celestial position (galactic latitude = +2.4 plus or minus 30 sec), luminosity (M sub v = -25.8 plus or minus 1.8), redshift (z = 0.0438), and radio emission (0.2-0.5 Jy). Counting rates in two energy channels are presented, and found comparable to the Type 1 Seyfert 3C120. Spectrophotometric calibration to an approximately 8 A resolution was also achieved. Attention is given to the close relation between X-ray emitting QSOs and Seyferts. |
