This option should be used with caution, as non-printingĬharacters should not be in the header in the first place, so this Substituting spaces for non-printing characters with fixHdr = Into the file until 2880 valid characters are present, or by Present is to pass values to fixHdr in readFITSheader.įixHdr attempts to fix headers with non-printing characters,Įither by removing them with fixHdr = 'remove', reading further passes additional values for file reading. One of the main selling points of the previous version of Mac OS X, 10.4 Tiger, was Dashboard. Phdu = 0 forces a read of a secondary HDU in aįairly pathological case (specifically: indicatingĪ read of a secondary HDU by setting NAXISn = 0 for n > 1, but NAXIS != 0Īnd NAXIS1 != 0.) This does not seem to be forbidden by the FITS QFitsView 13 is a FITS file viewer that is similar to SAOimage DS9. See the Example section forĮxample that includes file opening and closing. Isolated header units can be read with an appropriate combination of Files with more complicated structures or (HDU) pair from a file and returns a list with data, header, and axis ReadFITS is a simple but complete FITS file reader,Īutomatically detecting image and binary table data extensions Integer: maximum number of header lines to read.ĭeal with (illegal) nonprinting characters in the The first HDU, 2 for the second HDU, etc. Position of Header and Data Unit (HDU) in FITS file: 1 for ReadFITS ( file = "R.fits", hdu = 1, maxLines = 5000, fixHdr = c ( 'none', 'remove', 'substitute' ), phdu = 1 )Įxisting FITS file name, or remote file see examples.
