Current functions

At the moment, these are the current functions present in pyutils:

• pyadd: Sums the image data from the primary HDU of the given FITS files. Does not copy the information passed through the HDU header. The images must have the same size.
• date_time: Returns the current time in the following format: Current time: %Y - %m - %d – %H:%M:%S.
• pyselect: Returns the rows from the data of a FITS file that suits the conditions imposed by the arguments of the function.
• pymodhdu: Modifies the header of the extension of a FITS file using the parameters found in the arguments passed to the function.
• get_key_word: Returns the keyword from the header of a FITS file. If the extension is passed, will only search in that particular extension. If not, it'll loop over all the extensions until a match is found. If it's not found, an alternative output (in the form of a non-mandatory parameter) will be returned.
• pydump: Returns the raw values (as a list) of the column of the FITS file passed as argument.

• delete_data: Deletes rows or columns from the extension of a FITS file.
• create_fits_from_data: Creates a FITS file from the input data using an array-label system. NOTE: the extension will be nameless.
• filter_data: Filters 2D NumPy arrays or astropy.table.Table objects using the criteria passed to the function.
• imgstat: Provides statistics from FITS image files. Can be dumpled into a text file.
• merge_fits: Merges the specified data columns from several FITS files into a new file.
• add_column_to_fits: Adds a data columns to an existing data extension of a FITS file.
• add_row_to_fits: Adds a row or rows to the existing FITS file.
