Make Average
Procedure for making average fluxcal files for PPTA calibration
1. Log into newton
2. >cd /DATA/NEWTON_2/WRK1/HYDRA/
3. Set up links to observed Hydra cals.
First edit make_links to pick up desired files, then
>cd ..
>HYDRA/make_links
4. Clean up cal files
>cd HYDRA
>clean_cals
To watch progress of cleanCalFiles stage:
>tail -f cleanCal.log
5. Make .fluxcal files, compute Cal and Ssys flux densities and plot fluxcal spectra.
>make_fluxcals
6. List and sort .fluxcal files to form fluxcals.10cm etc.
>sort_fluxcals
Columns 4 & 5 and 6 & 7 are the cal equivalent flux densities in Jy and
their uncertainties for each channel (AA and BB respectively).
Columns 8 & 9 and 10 & 11 are the system equivalent flux densities in Jy and
their uncertainties for each channel (AA and BB respectively). The conventional
Ssys is col 8 + col 10.
The time sequence of cal flux densities can be plotted using gnuplot, e.g.:
>plot "fluxcals.10cm" using 2:4:5 w err,"fluxcals.10cm" using 2:6:7 w err
7. Investigate outliers in the Cal flux densities using spectra if necessary.
Delete the line from fluxcals.xxcm if not fixable.
10.Copy fluxcal lists to $PPTA/fluxcal/10cm etc.
>copy_lists
11. Copy fluxcals to PPTA/fluxcal/xxcm directories
>cd $PPTA/fluxcal/
>copy_fluxcals
12. Set up calavg lists and form avfluxcals, e.g.,
>cd 10cm
>ls -1 t12*.fluxcal > pdfb4_10cm_8.lis
and edit the list to form 3 or 4-month averages.
13. Edit do_calavg appropriatly and run to form the avfluxcals.
>do_calagv
14. Check with pacv, e.g.,
>pacv -D /null -o *.avfluxcal |grep -v pacv > avfluxcals.dat
and plot with gnuplot.
15. Repeat 12 - 15 for 20cm and 50cm.
