* utils: zea2healpix(): Implement inpainting missing pixelsAaron LI2016-10-102-3/+54
| | | | | | | The missing pixels in the reprojected HEALPix map are filled with the averages of their 8 neighboring pixels (excluding the NaN's if any). Also add the "--inpaint" argument to the executable script.
* utils: zea2healpix(): Average the duplicate pixelsAaron LI2016-10-101-2/+4
| | | | Also fix typos
* utils: zea2healpix() also return the mask arrayAaron LI2016-10-102-10/+18
| | | | | | | The mask array has values 0, 1, and 2, which indicate the different statuses of the reprojected HEALPix pixels. Also update the executable script to use the new return results.
* utils/reproject.py: Add more logging and some minor changesAaron LI2016-10-101-1/+22
|
* Add excutable script "bin/zea2healpix"Aaron LI2016-10-102-0/+89
| | | | | | | | The script takes the two ZEA-projected FITS images, reproject them to the full-sky HEALPix map in Galactic frame with RING ordering. TODO: * Add argument "--inpaint" after implement the inpainting function.
* utils/reproject.py: Implement zea2healpix()Aaron LI2016-10-102-0/+241
| | | | | | | | | | | | | | | | The "zea2healpix()" function reprojects the maps in ZEA (zenithal/azithumal equal area) projection to HEALPix data in Galactic frame with RING ordering. The other two helper functions "_image_to_healpix()" and "_convert_wcs()" are almost copied from the "reproject" project [1]. Thanks! TODO: * Add some more logging * Implement the "inpaint" argument to inpaint the HEALPix map if exists missing pixels [1] reproject: https://github.com/astrofrog/reproject
* utils: Preseve the dtype when read/write FITS filesAaron LI2016-10-104-24/+17
| | | | | | | | * utils/fits.py: hack the dtype to ignore the byteorder (FITS data use big endianness, e.g., dtype(">f4")) * utils/healpix.py: explicit convert the dtype and log the dtype * bin/healpix2hpx, bin/hpx2healpix: remove the --float argument * other minor fixes/updates
* Use newly added "read_fits_healpix()"Aaron LI2016-10-092-15/+8
| | | | Also remove a unused variable in "galactic/synchrotron.py"
* utils/fits.py: read_fits_healpix() also accept HDUAaron LI2016-10-091-4/+9
|
* utils: Add function "read_fits_healpix()"Aaron LI2016-10-092-1/+30
| | | | | | This function wraps on the `healpy.read_map()`, but reset the data array to its original dtype in FITS file, as well as return the FITS header in `astropy.io.fits.Header` object.
* utils/healpix.py: fix logging import; minor style fixesAaron LI2016-10-091-10/+5
|
* Update to use the "write_fits_healpix()" functionAaron LI2016-10-052-22/+7
|
* utils: Add "write_fits_healpix()" to replace "healpy.write_map()"Aaron LI2016-10-052-0/+101
| | | | | | NOTE: This "write_fits_healpix()" function only implements the most common case of the HEALPix FITS style.

|
* configs/manager.py: Add method "get_path()"Aaron LI2016-10-041-0/+21
|
* configs/manager.py: Add method "read_userconfig()"Aaron LI2016-10-041-3/+35
| | | | | | | | This "read_userconfig()" method is specifically used to load the user configuration file, and record the absolute path of the configuration file, which allows the use of relative path to specify the input files (e.g., galactic/synchrotron/template) for simulation within the configurations.
* configs/validate.py: Explain these checkers differ to Validator'sAaron LI2016-10-041-1/+7
| | | | | | NOTE: these checker functions check on the whole configuration, and have no relation to the checker functions of the `Validator` class.

|
* configs/manager.py: Add "frequencies" propertyAaron LI2016-10-041-0/+16

* Makefile: Add variable "VENV" to control virtualenvAaron LI2016-10-031-8/+18
| | | | | | | * The variable "VENV" (default: "venv") defines the virtualenv name and can be override by the environment. * Add "devbuild" target to menu. * Remove the "--user" argument to fix the pip install problem.

| | | | Also unify the quote style.
* configs/manager.py: Update docstrings.Aaron LI2016-09-301-2/+21
| | | | The NumPy docstring style is used.

|
* utils/logging.py: Save existing formatter for new handlersAaron LI2016-09-291-0/+5
| | | | | | | By saving the existing formatter and setting for the new handlers, the configured format styles are kept. Otherwise, the newly created handlers does not have a formatter, thus the default format style gets used.
