step | purpose | What you have to do |
setup | have your own data_rep on your account. Follow the setup advice. For analysing of large data sets make sure to use a sufficient machine (e.g. isdcul10, crab, etc.) | |
setenv COMMONLOGFILE mylog.txt | define a logfile | If you want to have a log file, set it now. To unset it later just type "unsetenv COMMONLOGFILE" |
emacs dols.txt | create a list of SCWs | Here are four examples, for 60Co, 137Cs, 241Am, and 24Na. The SCW number now corresponds to the RUN number from the Bruyeres-le-Chatel logbook but very long pointings have been split into several SCWs. You can access the complete Bruyeres-le-Chatel SPI calibration logbook as an ASCII file. Do not use the following science windows: 146 (last valid SCW / BLC run number is 410). Data should now be useful up to run number 410! For your planning also the Daily Task Plan for BLC might be useful. |
og_create idxSwg="dols.txt" ogid="obs_id" baseDir="." | create the OG | give a (up to now not existing!) name for the obs-branch (obs_id). |
cd obs/obs_id | go to your obs branch. | |
cp $ISDC_ENV/source_cat_in.fits . | copy source catalogue | Analysis is faster if you give to SPIROS and SPISKYMAX an input catalogue. This catalogue is assuming that the source is at position [0;0], which is true for BLC calibration. |
blc_sa (if you want to avoid the GUI, unsetenv DISPLAY before starting blc_sa !) |
do the analysis | start with blc_sa, fill in the parameters for the analysis. You can also use prepared blc_sa parameter files for the different sources used during calibration (copy the par file to blc_sa.par in your $PFILES directory). You can get a detector list if you are not familiar with our pseudo-detector scheme. Which IRFs do you want to use? Begin with small numbers of energy bins! Read also the SPIROS documentation. |
... | wait | be patient! |
fv spi/source_res.fits ... |
output check | read the log file, check the images, events table and so on. If it is failing - check for missing/wrong input parameters first. In case you do not understand the problem, send the logfile and the parameter file and we will try to find out what went wrong. |
blc_sa | step back and redo parts of the analysis | Run blc_sa again. Give the start level you want to begin with (e.g. when you want to define another binning of the data, start with BIN_I) and end-level (e.g. IMA). If this crashes, you have to remove everything and start from og_create again. |
