beam_sample

edge_pydb.beam_sample.beam_sample(edgetab, gallist=None, columnlist=None, beam_orig=7, beam_final=20, outfile=None, doplots=False, pdfprefix='beamsample', nx=5, ny=4)

Process one or more galaxies from an allpix HDF5 file and output central surface brightness after convolution to a user-specified Gaussian beam. The pixel with the smallest value of rad_arc is used as the center; this should be recalculated using gc_polr (conversion.py) beforehand if the default central pixel is not desired.

Parameters:

edgetabEdgeTable

Table, extracted from an allpix HDF5 file

galliststring or list of strings

List of galaxy names to process. Default is to process all galaxies.

columnliststring or list of strings

List of columns in the table to process. Default is to process all columns, excluding the initial coordinate columns. NOTE: Use caution when convolving non-flux columns.

beam_origfloat

The FWHM of the original beam in arcsec. Default 7”.

beam_finalfloat

The FWHM of the target beam (to convolve to) in arcsec. Default 20”.

outfilestring

The name of the output table. Default is not to write the table.

doplotsboolean

Whether to output plots for debugging purposes

pdfprefixstring

Prefix for plots if doplots=True. The galaxy name is appended to the prefix.

nxint

number of sub-panels in x direction

nyint

number of sub-panels in y direction

Returns:

taboutTable

Astropy table with the results
