... New Mandatory Keyword for COS Observations Describing whether Targets are Point Sources or Extended . ... Both COS FUV and NUV observations of targets with FWHM larger than about 0.6 arcsec or radius larger than 0.35 arcsec should be considered as extended. ... If this new target-level description keyword is not provided, APT will trigger a warning message asking the PI to define it, and any proposals submitted without a value specified for all COS targets will be sent back to the PI to be corrected...

... To address the problem of point-source photometry in restored images Lucy (1994) suggested a two-channel photometric restoration method in which the points are represented as functions in one channel and the background, constrained to be smooth by an additional entropy constraint, in the other. ... In the new CPLUCY implementation the stars can be at arbitrary x , y sub-pixel positions but the entropy constraint on the background, used by PLUCY, is retained. ...

The technical memorandum: A Kernel Model for Precision Timekeeping (PostScript) describes an engineering model which implements a precision time-of-day function for a generic operating system. ... The model changes the way the system clock is adjusted in time and frequency, as well as provides mechanisms to discipline its time and frequency to an external precision timing source, such as a pulse-per-second (PPS) signal. ...

Next: Reduce point data Up: Quick Guide Previous: Print form sheets Contents . You should reduce this data of type ``scan'' before anything else. ... Plot the background rate (four channels at a time) versus time. ... Use P ROCESS BG if you want to replace edited scans with an average value from other valid scans in the same channel. ... The reason for reducing the background data first is that average will not average the point data of a scan for which no background data exists. ...
