... On 04jan01 through 08jan01 a number of calibrator sources were tracked using the sband narrow receiver at 2380 Mhz and the standard calibration pattern (4 cross scans at 45 degrees to one another). ... Figure 1 shows the point source gain in K/Jy versus azimuth angle. ... Figure 2 shows the same point source gain in K/Jy versus zenith angle with the bottom plot coming from the sep00 run. ... The ratio of the beam efficiency to the point source gain is independent of the source flux. ...

In this section we present plots which may be used to rapidly estimate signal-to-noise ratio (SNR) for point sources with stellar spectra observed through popular WFPC2 filters. ... One uses these plots as follows: . ... Dotted lines across the top of each plot indicate the onset of saturation. ... We look at Figure B.10 and find this value on the horizontal axis. ... This exposure is well below the saturation lines in the plot, so saturation is not a concern. ... 0.45 Figure B.1: Point Source SNR vs. ...

... There are several explanations for these X--ray quiet PMS stars. To examine the explanations, it is proper to divide the PMS stars into three groups: those bluer than R - I = 0.7, those redder than the X--ray sources (R - I > 1.25) and those with colors similar to the X--ray sources. ... A total of 26 of the non--X--ray detected PMS candidates had spectra taken. ... Between V=14 and V=16, I find 25 stars which are X--ray sources and estimate 19 non--X--ray PMS stars. ...

XMM-Newton Science Analysis System . ... A different approach is done via the setting withctisrcpos =Y: all event energy corrections do not use the actual RAWY coordinate but the corresponding RAWY location of the source ( SRCPOS ) as determined by the task epframes (either automatically or via setting withsrccoords =Y). ... The task epchain may be used with the setting ccds =4 withctisrcpos =Y to process only the CCD 4 where usually the bright source is located that causes the Out-of-Time events. ...

... Optical Counterparts for 70,000 Radio Sources: APM Identifications for the FIRST Radio Survey . ... We describe a program to identify optical counterparts to radio sources from the VLA FIRST survey using the Cambridge APM scans of the POSS-I plates. We use radio observations covering 4150 square degrees of the north Galactic cap to a 20 cm flux density threshold of 1.0 mJy; the 382,892 sources detected all have positional uncertainties of Format for the Table of FIRST-APM Optical Counterparts . ...

As for soft/hard limits, ulimit -S vs. ulimit -H ought to do that. Incidentally, if you specify neither, both should get changed at the same time. csh is an excemption; here you need to use limit -h for hard limits. ...
