This is a collection of modules for analyses related to astrophysics by Dr. Kornpob Bhirombhakdi. Contact: kbhirombhakdi@stsci.edu
Tasks include:
- dqmask.py = handle data quality (DQ) arrays
- container.py = handle declaring attibutes given keys and values
- segmentation.py = wrapper for making a segmentation map (used to be source.py in version < 1.2.0)
- sub2full.py = mapping a subarray image back to its full frame
- gnd.py = wrapper, and main class for grism reduction
- grismconf.py = read conf file for grism reduction
- grismsens.py = read sens file for grism reduction
- grismapcorr.py = read aperture correction table, and calculate aperture correction factor
- grismmeta.py = construct meta info
- make_sip.py = calculate Simple Imaging Polynomial (SIP)
- photapcorr.py = read photometric calibration table, and prepare calibration factors (i.e., encircled energy correction, and photometric AB zeropoint)
- mag2flux.py = converting ABmag to flam
Known issues:
- ACS photometric zeropoints are set to 0.
- Memory
- No description/documentation
- Handling other telescopes
- flux2mag.py
- AB2Vega.py
- Vega2AB.py
- WFC3 subarray
- drz gets brighter about 10%
- test new code with ACS-WFC, and other WFC3-IR
Next
- Combine 1D spectra
- Use assertion for error handling (http://swcarpentry.github.io/python-novice-inflammation/09-defensive/index.html)
- HST-ACS-WFC flux calibration
- Fix drz getting brigther
