For more information please read the individual help files of the programs used (e.g. blc_sa --help).
| step | purpose | What you have to do |
| setup | have your own data_rep on your account. Follow the PLC setup advice. Make sure to use a sufficient machine (e.g. isdcul10, isdcul19, 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 | prepare a list of SCWs | create a list of SCWs. Here is one example for a valid list of three SCWs: dols.txt. Please have a look on the list of usable PLC data. Please also note that the source was to near to the mask to get highly meaningful images out of SPIROS and SPISKYMAX |
| 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/help/source_cat_in.fits . | copy source catalogue | Analysis is faster if you give to SPIROS and SPISKYMAX an input catalogue. This catalogue is using one of the source positions as seen by SPI during the PLC. |
| 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 (either off-line using an editor, or by using the GUI which will appear on the screen). The following parameter file can be a basis for your analysis: blc_sa_plc.par (if you want to use it, copy it to $PFILES/blc_sa.par). For different sets of detectors you need different response (IRF). 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! |
| 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. |
| 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. |
