Timing ll radio telescope data collection systems use a P s internal clock to apply timestamps to the data. Each P runs a service, Meinberg NTP daemon, to keep its system clock within a few milliseconds of UT using Network Time Protocol (NTP). The NTP server is a GPS-ntp-pi stand-alone unit using GPS and GLONSS signals to determine and provide the correct time on the local network. Future work includes upgrading the spectrographs to a GPS-based hardware system with firmware modification to keep the start of each frequency sweep disciplined to within a hundred nanoseconds of UT. For more information, see: GPS-NTP Pi For more information, see: Meinberg NTP Server and Meinberg NTP Server Monitor Page 2 of 27
5 alibration ll radio telescope systems are calibrated in terms of antenna temperature using a noise source of known temperature calibrated against a 5722 noise diode. n automatic calibrator runs a step calibration on all receivers a fixed number of hours before and after Jupiter transit (usually 3 hours when Jupiter s elongation is < 90 and 4.5 hours when Jupiter s elongation is > 90 ), every day. The step cal runs in 17 steps of 5 seconds each separated by 3 d, ranging from 4.3 kk to 250 MK equivalent antenna temperature. For more information see: 5722 Noise Generator For more information see: J4O utomatic alibrator omputers Three identical Ps are used to record data from the receivers. Each has a 2.4 GHz M Opteron dual-core processor, 4 G RM, and a 1 T hard drive. ll run Windows XP SP3. ll are connected to the observatory LN. Internet The observatory has internet access via a 6 Mbps SL connection. This connection allows the Radio Sky Pipe (RSS) and Radio Sky Spectrograph (RSS) software to serve data to interested remote observers. Power The receivers, computers, and network hardware are fed by three 1.5 kv battery backup units providing at least 15 minutes of power if the mains fail. Operations Several radio telescopes operate all day, every day (see Receivers above). Useful Jupiter observations are made any time Jupiter is within 3 hours of transit, but this is extended to around 4.5 hours when Jupiter s transit elevation is greater than 70 and Jupiter is near opposition.

27 What is Magnetic eclination? 2 of 2 Page 03/31/ of 23:25 27 Negative declination (WEST) Positive declination (EST) How can we calculate declination at any given place? One way would be to use declination maps. Unfortunately because of secular variation, declination values are constantly changing. When printed maps were the only way of getting this information, the declination values were somewhat out of date by the time the maps got to the general public. nother way would be to perform a prediction. This should be based on a world-wide empirical model of the deep flows. This web page operated by the National Geophysical ata enter (NG) offers a pretty good value for declination. The model reflects a highly predictable rate of change, and will usually be more accurate than a map, and almost never less accurate. The best way however is to use the current web site, which offers in a graphical format using Google Maps PI the computed declination for any place on Earth. The algorithm implements the World Magnetic Model WMM2015. opyright 2015 Magnetic-eclination.com
