Scope
This document provides a description of the algorithm and instructions for the correct usage of the
CATPREP task, which is part of
eSASS (the
eROSITA Science Analysis Software System).
Description
CATPREP is part of the catalogue tools of
eSASS. The tool will convert the output of
ERMLDET into the catalogue file format with one source per row.
NOTE: the string written to column DETUID in user-command mode is different to that written to this column by the pipeline.
Input Parameters
- infile (string array) REQUIRED [e.g. "mllist.fits"]
- Input file (this is expected to be the output file from ermldet).
- outfile (string) REQUIRED [e.g. "catsrclist.fits"]
- The primary output source catalogue.
- clobber (boolean) OPTIONAL [default: yes]
- If the output file already exists, then setting clobber = 'yes' will cause the file to be overwritten.
- det_algo (string) OPTIONAL [default: ML]
- Abbrevation of the detection algorithm. Used only in generating the DETUID column.
- detuid_prefix (string) OPTIONAL
- String to be prepended to detuid IDs (non-pipeline mode).
- p_srcdensity (integer) OPTIONAL [default: 10]
- Xth nearest neighbour to derive local srcdensity.
- outfile2 (string) OPTIONAL [e.g. "mpe_catsrclist.fits"]
- Name of a separate outfile to which an owner and flux filter will be applied.
- owner (integer) OPTIONAL [0, 1, or 2. Default: 0]
- For outfile2: filter source catalogue to keep only sources which belong to 1=IKI, 2=MPE, 0=nofilter.
- flux_threshold (real) OPTIONAL [e.g. 0.0 (also the default)]
- For outfile2: flux_threshold (ML_FLUX_0) to be applied to outfile ownerflag .
Known Issues:
None.
