-====== v252i ====== 
- 
-[[http://​www.atnf.csiro.au/​vlbi/​wiki/​index.php?​n=LBANov2008.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
