Warkworth 12M

Using the DBBC as a power meter, we take the total power in a IF. As this is a log response have to convert log to linear within the FS (antcn). Via this method we have used the following sources for pointing in X-Band.

We started in S-Band by using the “moon”. Once we had some offsets we moved on to the other sources to refine the offsets required. Once we had reasonable offsets we started using aquir to run fivpt / onoff over a 24hr period for visible sources.

Seen in S and X: Taurus A, Orion A, 3C273b, Virgo A, Cent A, Cyg A, Cas A, CTB31

Seen in S: W43, CTB32

Seen in X: ngc3603

To get detections by fivpt in the field system we used the following:

 Record:  Step  Int(s)  Steps Band
 centa    0.40  10            x-band
 oriona   0.40   1            x-band
 3c273b   0.40  10            x-band
 taurusa  0.4    1            x-band
 ctb31    0.5    8       11   x-band 
 ctb31    0.4    1       11   s-band

Step - decimal fraction of beam Int - in seconds, DBBC gives a total power reading for an IF each seconds Steps - how many steps for the scan through the source
