| - | ====== 50 cm Polarisation Project ====== | ||
| - | The Effelsberg 100-m will be equipped with a 50cm receiver (300 -- 900 MHz band). One of the main scientific drivers for the receiver is to carry out a large scale polarisation survey of the sky. | ||

| - | ===== 50cm Rx Technical details (Frontend) ===== | ||
| - | |||
| - | The bandwidth, filter specs and other details on the receiver are on this page: https://eff100mwiki.mpifr-bonn.mpg.de/doku.php?id=electronics:50cmsystemeff (**NOTE:** You should have an account on the Effelsberg-100m Wiki to access this page). | ||

| - | ===== Pulsar Digital Filterbank in Spectrometer mode (Backend) ===== | ||
| - | |||
| - | The Pulsar Digital Filterbank version 4 (PDFB4) is a fast dump spectrometer, that can be used for the polarisation survey by adjusting the firmware accordingly. The [[pulsarinstruments:DFBSpectro | PDFB4 Spectrometer]] page has details on operating the instrument in this mode. | ||

| - | ===== Observing tools ===== | ||
| - | - http://www.narrabri.atnf.csiro.au/cgi-bin/obstools/obsability.pl lets you plot the elevations of various sources during the observing run. The Effelsberg radio telescope lies at latitude 50:31:29 , longitude 6:52:58 and altitude 319. | ||
| - | - {{:projects:eff_hor.ps|}} allows for a quick conversion between the hour angle and declination of a source to its azimuth and elevation, as seen from Effelsberg. Also shown are the east and west optical horizons (as seen from the bottom of the dish). Azimuth goes from 160 degrees (left) to 20 degrees (right) in steps of 20 degrees, and elevation from 10 degrees up to 80 degrees in steps of 10 degrees. | ||
