This is a collection of modules for analyses related to astrophysics by Dr. Kornpob Bhirombhakdi. Contact: [e-mail]

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

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

v.2.5.0

- Implement grismmodel.py

- Implement GND.make_localbkg()

- Change GrismMeta.make_grismNdirect to GND.make_grismNdirect

- Change dqmask.py implementation

v.2.4.0

- Implement grismmeta.py

- HST-ACS-WFC is available for wavelength calibration, but not flux calibration

- HST-ACS-WFC subarray is applicable

- Change the construction of GrismCONF, and GrismSens

v.2.3.0

- GND.make_pairs(pairs=None) can automatically make pairs

- GND.make_xyd(xyd=None, init=init, inittype='radec') can automatically find a centroid given init

- GND.show(method='meta', output=True) returns the table instead of displaying it

- GND.make_drz() is deactivated

v.2.2.0

- GND.save takes filename

- Fix GND.show(method='flam') handling xmin, xmax
