The pipeline by default interpolates across the bad columns in the REDL CCD when it creates the master bias, but does not so when it processes the science data. This inconsistency can create boxy emission-like features as seen in the figure below. ...

The overall efficiency (including atmospheric transmission, reflectivity of the telescope mirrors and overall efficiency of the optics and of the detector) for broad-band imaging should be about 25% in H and K, and about 15% in J. The main noise source for both broad- and narrow-band imaging should be the photon noise associated to the background+source flux. ... Flat fielding (and possibly background subtraction) might increase the noise by a factor 2 ? ...

Next: The Model Up: No Title Previous: Radiopulsars as Sources of . In this section, we study the evolution of stellar populations on a time-scale of 10 Myr for a starburst љ occurring under conditions similar to those in the Galactic Center (see Lipunov et al. (1995d)[ 126 ]). We estimate the expected number of X-ray transient љ sources (NS + MS star), super accreting BH, and BH + supergiant binaries, all as functions of time elapsed after the burst. ...
