A Pipeline for the ROTSE-IIId Archival Data
We have constructed a new, fast, robust and reliable pipeline to detect
variable stars from the ROTSE-IIId archival data. Turkish share of ROTSE-III
archive contains approximately one million objects from a large field of view
(1.85\dgr) and it considerably covers a large portion of northern sky
(\delta>-25\dgr). The unfiltered ROTSE-III magnitude of the objects ranges
from 7.7 to 16.9. The main stages of the new pipeline are as follows: Source
extraction, astrometry of the objects, light curve generation and inhomogeneous
ensemble photometry. A high performance computing (HPC) algorithm has also been
implemented into the pipeline where we had a good performance even on a
personal computer. Running the algorithms of the pipeline on a cluster
decreases analysis time significantly from weeks to hours. The pipeline is
especially tested against long period variable stars with periods of a few
hundred days (e.g Mira and SR) and variables having periods starting from a few
days to a few hundred days were detected.Comment: 8 pages, 5 figures 2 tables; last revision before publishe
