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 catalog tools of
eSASS. The tool will convert the output of ermldet into the catalog file format with one source per row.
NOTE: DETUID is a column generated in the pipeline mode of eSASS and therefore DETUIDs between pipeline-catalog-lists and user-catalog-lists will vary.
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 catalog.
- 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]
- For outfile2: filter source catalog to keep only sources which belong to 1=IKI,2=mpe, 0=nofilter.
- flux_threshold (real) OPTIONAL [e.g. 0.0]
- For outfile2: flux_threshold (ML_FLUX_0) to be applied to outfile ownerflag .
Known Issues:
- If you leave outfile2 at default (the empty string) this causes the task to try to write to an empty file name.
