unable to plot parkes dfb3 spectra

[jackson@…]

I am following all of the on-line examples. All I want to do is to plot an on-off spectrum. I use scantable to read in the data scan = scantable('/DATA/PKCCC3_4/2008-06-18_0714_P632_G328.80+0.64a') but when I try anything else such as q = scan.auto_quotient() I get RuntimeError: Selection contains no data. Not applying it. or scan.summary() I get RuntimeError: Couldn't convert frequency frame.

It surely should be easy to see the data...There is no other online display that works, and it would be nice to see something, anything, about the data quality.

Help would be most appreciated.

Regards, Jim Jackson

Hi Jim,

here is a workaround until I figure out why it doesn't work.

scan = scantable('/DATA/PKCCC3_4/2008-06-18_0714_P632_G328.80+0.64a')
scan.summary() # look at the scan numbers for the source and reference scans
# Then select them (here only one on/off)
src = scan.get_scan(1)
ref = scan.get_scan(0)
q = quotient(src, ref)

Malte.
