v252i

Observers wiki

Observing at 8.4 GHz.

ATCA reference station is W104 (CA01).

Tid 70m (DSS43) recorded from about UT 1110 onwards.

Correlation notes

4 subbands, RCP only. Correlated with 64 spectral channels per 16 MHz subband, 2s integration.

PI (Roopesh Ojha) wants data in UVFITS format.

Output files:
v252i.rpf
v252i_2.rpf contains last 5 hours with 1 microsecond clock offset to O'Higgins

NB. ATLOD crashes - due to file being too large to read in in one go? Using timerange selection (e.g. 12h at a time) OK.

Converted to v252i.uvfits - read this in with FITLD for analysis

Brief Data Summary

Scan listing

Plots of autocorrelations

Comments: Bumps in ATCA bandpass; band inversion also? OH and TC bandpass also looks peculiar

Plots of uncalibrated amplitude and phase against frequency

Comments: Looks generally Ok except similar occasional bumps in ATCA baselines

Plots of uncalibrated amplitude and phase against time

Comments: Looks Ok

Fringe-fit delay solutions

Comments: Ok

Fringe-fit phase solutions

Comments: Ok

Fringe-fit rate solutions

Comments: Ok

Plots of Amplitude and phase against frequency with fringe-fitted solutions applied

Comments: Again the same dip/rise in the baselines to ATCA

Plots of Amplitude and phase against time with fringe-fitted solutions applied

Comments: Ok
