- msfc_ccd.fits.open(path, camera=None, axis_x='detector_x', axis_y='detector_y')[source]#
Load the given FITS images into memory.
This is a convenience function for
msfc_ccd.SensorData.from_fits().- Parameters:
path (str | Path | AbstractScalarArray) – Either a single path or an array of paths pointing to the FITS files to open.
camera (None | AbstractCamera) – A model of the camera used to capture the images being loaded. If
None(the default), themsfc_ccd.Camerawill be used.axis_x (str) – The name of the logical axis representing the horizontal dimension of the images.
axis_y (str) – The name of the logical axis representing the vertical dimension of the images.
- Return type:
Examples
Load and display a single FITS file.
import matplotlib.pyplot as plt import named_arrays as na import msfc_ccd # Load the sample image image = msfc_ccd.fits.open(msfc_ccd.samples.path_fe55_esis1) # Display the sample image fig, ax = plt.subplots( constrained_layout=True, ) im = na.plt.imshow( image.outputs.value, axis_x=image.axis_x, axis_y=image.axis_y, ax=ax, );
Load and display an array of two FITS files.
import numpy as np import named_arrays as na import msfc_ccd # Define the name of the time axis. axis_time = "time" # Define the array of two sample FITS files path = na.ScalarArray( ndarray=np.array([ msfc_ccd.samples.path_fe55_esis1, msfc_ccd.samples.path_fe55_esis3, ]), axes=axis_time, ) # Load the sample images image = msfc_ccd.fits.open(path) # Display the sample images fig, axs = na.plt.subplots( axis_rows=axis_time, nrows=image.outputs.shape[axis_time], sharex=True, constrained_layout=True, ) im = na.plt.imshow( image.outputs.value, axis_x=image.axis_x, axis_y=image.axis_y, ax=axs, );
