Parameters used for each frame type (bias, pixelflat, etc) are abstracted to a single "Frame-Group" parameter set. The default is 'bias'; valid frame types are shown using the static method valid_frame_types
(see below). The parameters used to process the images in the frame group is a subset of FrameGroupPar
, called ProcessImagesPar
.

CalibrationsPar is a super set of other parameter groups that are needed for the calibration data. It is built up of 10 other parameter sets, plus a few additional single parameters like where to save the master frames. Six of these are instances of FrameGroupPar
for the bias, arc, pixelflat, pinhole, trace and standard frames (see above). The remaining four set how to peform the field flattening (FlatFieldPar
), determine the wavelength solution (WavelengthSolutionPar
), trace the spatial position of the slits along the dispersion axis (TraceSlitsPar
), and trace the shift in the wavelength solution as a function of spatial position within a slit (WaveTiltsPar
)

Like all the other pypit parameter sets, PypitPar
has a from_dict
method, but it also has a from_cfg_file
that allows you to read and write the full parameter sets to a *.cfg
config file. However, for runs of pypit, we're most often going to be reading the configuration from a group of lines in the *.pypit
file. Here's a short demo of how to read and write the pypit parameters to a *.cfg
; writing may be useful to see the full set of parameters along with the description of each parameter.
In [19]:
help(pypitpar.PypitPar.from_cfg_file)
Help on method from_cfg_file in module pypit.par.pypitpar:
from_cfg_file(cfg_file=None, merge_with=None, evaluate=True) method of builtins.type instance
Construct the parameter set using a configuration file.
Note that::
default = PypitPar()
nofile = PypitPar.from_cfg_file()
assert default.data == nofile.data, 'This should always pass.'
Args:
cfg_file (:obj:`str`, optional):
The name of the configuration file that defines the
default parameters. This can be used to load a pypit
config file from a previous run that was constructed and
output by pypit. This has to contain the full set of
parameters, not just the subset you want to change. For
the latter, use :arg:`merge_with` to provide one or more
config files to merge with the defaults to construct the
full parameter set.
merge_with (:obj:`str`, :obj:`list`, optional):
One or more config files with the modifications to
either default parameters (:arg:`cfg_file` is None) or
the parameters provided by :arg:`cfg_file`. The
modifications are performed in series so the list order
of the config files is important.
evaluate (:obj:`bool`, optional):
Evaluate the values in the config object before
assigning them in the subsequent parameter sets. The
parameters in the config file are *always* read as
strings, so this should almost always be true; however,
see the warning below.
.. warning::
When :arg:`evaluate` is true, the function runs `eval()` on
all the entries in the `ConfigObj` dictionary, done using
:func:`_recursive_dict_evaluate`. This has the potential to
go haywire if the name of a parameter unintentionally
happens to be identical to an imported or system-level
function. Of course, this can be useful by allowing one to
define the function to use as a parameter, but it also means
one has to be careful with the values that the parameters
should be allowed to have. The current way around this is
to provide a list of strings that should be ignored during
the evaluation, done using :func:`_eval_ignore`.
.. todo::
Allow the user to add to the ignored strings.
Returns:
:class:`pypit.par.core.PypitPar`: The instance of the
parameter set.
You can get the default parameters and print the result like this.
In [20]:
# Write the defaults
p = pypitpar.PypitPar.from_cfg_file()
p.to_config('default.cfg')
You can then read it back in. The expand_spectrograph
option allows you to set all the spectrograph setting using the spectrograph
keyword in the input config file (this is KECK_LRISb
by default). If you just want to use what's in the config file without finding the spectrograph configuration file (because those keywords are already in the configuration file in this example), you would set expand_spectrograph=False
.
In [21]:
# Read them in
p = pypitpar.PypitPar.from_cfg_file('default.cfg')
p['rdx']['spectrograph'] is None

I actually had to comment out the definition of the flexure spectrum because I can't find it on my disk, and the declaration above faults when it can't find the file.
With the declaration above, all the default parameters are set, the spectrograph key (KECK_LRISb
) is used to find the appropriate spectrograph definition file (../../pypit/config/spectrographs/KECK_LRISb_spectrograph.cfg
), and both are merged with the alterations in the local keck_lris_blue_long_400_3400_d560.cfg
file.
You can print the compiled parameters using the to_config
method.

p.to_config('compiled_example.cfg')
