diffpanstarrs 0.11

Downloads Pan-STARRS data around given coordinates and performs difference imaging to extract light curves

diffpanstarrs

A small utility package to download and process Pan-STARRS data in the sense of difference imaging.

Installation

Simply clone and install using pip:

  git clone [e-mail]:dux/diffpanstarrs.git
  cd diffpanstarrs
  pip install .

Requires python ≥ 3.7.

One must also have a working installation of sextractor. For now, sextractor must be set in the path under the aliases sex or sextractor.

Usage

See the example in tests/test_simple_download_and_process.py:

from diffpanstarrs import downloadAndProcess

# feed the routine all the parameters like the coordinates, the size of the
# images to download, which color channels, etc.
res = downloadAndProcess(RA=69.5619,
                         DEC=-12.28745,
                         hsize=512,
                         workdir='myworkdir',
                         name="HE0435-1223",
                         channels=['g'])
# plot the light curves:
res.plotCurves()
# plot the difference images and variability image:
res.plotDiffImg(crop=30)
