... HST . Errors in Processed TIME-TAG Data from STIS Now Corrected . ... Data . ... HST Peer Review Process . ... HST Overview . ... The previous ground processing software failed to properly trap these errors. As a result, gaps or jumps in time could occur in processed TIME-TAG data. ... All investigators working with STIS TIME-TAG data should read the more detailed discussion of possible problems, and if they believe that their data may have been affected, retrieve it again from the archive. ...

About the only thing that can go wrong is not having the pulsar details correct in the catalogue OR not integrating for long enough. ... You can check what the catalogue thinks it knows about the pulsar by using psrinfo and typing . ... NSUB: - Number of frequency sub-bands . ... Note if you are reducing this data at Parkes you will have to copy psrcat.unformatted back up to $PSRHOME/soft/psrinfo at Parkes before rerunning tarchfb_driver.

... The PROS system provides the capability to keep track of the uncertainties in image files through error arrays. ... There is a task, errcreate , that will estimate the errors in an image and produce an error array. ... Some tasks that transform images, such as imsmooth, imcompress , and imreplicate have the option to produce a resultant error array, derived from the original image's error array. Note, however, that the imcalc task does not produce an error array. ...

... A dynamo (or electric generator) is a device converting . ... Faraday discovered that by moving a magnet next to a closed electric circuit, or changing the magnetic field passing through it, an electric current could be "induced" to flow in it. ... Faraday's disk dynamo Faraday showed that another way of inducing the current was to move the electric conductor while the magnetic source stood still. ... Faraday's disk dynamo needs a magnetic field in order to produce an electric current. ...

This module provides for execution of CGI scripts. ... Module Identifier: cgi_module Any file that has the mime type application/x-httpd-cgi or handler cgi-script (Apache 1.1 or later) will be treated as a CGI script, and run by the server, with its output being returned to the client. ... Debugging CGI scripts has traditionally been difficult, mainly because it has not been possible to study the output (standard output and error) for scripts which are failing to run properly. ... Status: mod_cgi . ...

Symptoms of this problem include the above message in the error log and zero-length responses to non-zero-sized files. ... A Permission denied error in the error_log , accompanied by a Forbidden message to the client usually indicates a problem with your filesystem permissions, rather than a problem in the Apache HTTP Server configuration files. ...

... Discusses the role of a pipeline in the AXAF Science Center Data System. Due to the complexity of the application, a prototyping effort was initiated to evaluate the risks involved with portability, open architecture, error handling/recovery, and distributed processing. Processes in the pipeline are initiated and monitored by a process control application developed using Perl. ... During that time, a Process Control application was developed to allow us to assess the risk factors. ...

Most radio and modem clocks used for a primary (stratum-1) NTP server utilize serial ports operating at speeds of 9600 baud or greater. ... In order to reduce these errors, a set of special line disciplines and stream modules can be configured in the Unix kernel. ... Note that not all Unix kernels support line disciplines and of those that do, not all support System V streams. ... There are two line disciplines and a special streams module included in the distribution. ...

... Computing the pointing error . ... The platform can be rotated by pulling on the tie downs or redistributing weight on the platform. ... The horn rotates through the same angle as the platform. ... The plots show the computed pointing error for different platform rotation angles (.ps) ( .pdf ): . This shows the pointing error in as you tilt the platform. ... B2209+080 has the pointing errors with no tilt. ... The computed pointing error for a platform tilt track the measured errors pretty well. ...

... The choice of which type of electricity is called "positive" and which "negative" was made around 1750 by Ben Franklin, early American scientist and man of many talents (the stamp on the left commemorates his role as first US postmaster--and colonial postmaster before that). ... Franklin knew of two types of electric charge, depending on the material one rubbed. ... Later, when electric batteries were discovered, scientists naturally assigned the direction of the flow of current to be from (+) to (-...

Sloan Digital Sky Survey Telescope Technical Note 19970527 Walter Siegmund . ... Pointing Error Budget . ... The interleaved strips and adjacent stripes overlap about 1 arc minute. ... However, a 2-D pointing accuracy of 3 arc seconds RMS leads to acceptibly uniform overlap and minimises the number of cases that require special handling (Table 3). ... A guide fiber bundle diameter of 16.5 arc seconds and a pointing accuracy of 3 arc sec RMS results in 99% initial success in acquiring guide stars. ...
