read_header_keywords_lisobs

raccoon.fitsutils.read_header_keywords_lisobs(lisobs, kws, notfound=nan, ext=0, names=None, index=None)

Read keywords in kws from FITS header for the observations in lisobs.

Parameters:

lisobslist of str or list of astropy header object (astropy.io.fits.header.Header): List of the FITS files from which to read the header or list of astropy header objects (faster if header already loaded before). If it is a header object, the parameter ext is not used.
kwsstr or list-like
notfoundany (default np.nan): Value to write in the output if the keyword is not found in the header.
extint, str (default 0): Extension of the FITS from which to get the header.
namesdict: Names for the output dictionary keys, to substitute the original header keywords. E.g. names={‘oldk: ‘newk}. Must contain all the keywords in kws. If not a dictionary or old keywords not correct, no change is made.
indexlist-like: Used if want the returned dataframe to have a specific index. If None and list of observations provided, index will be the observations names (path + file name). If None and headers provided, index will be numeric.

Returns:
