List of Routines

• FXBCLOSE Close a FITS binary table extension opened for read. Closes a FITS binary table extension that had been opened for read by
• FXBREADM Read multiple columns/rows from a disk FITS binary table file. A call to FXBREADM will read data from multiple rows and multiple columns in a single procedure call. Up to fifty columns may be read in a single pass; the number of rows is limited essentially by available memory. The file should have already been opened with FXBOPEN. FXBREADM optimizes reading multiple columns by first reading a large chunk of data from the FITS file directly, and then slicing the data into columns within memory. FXBREADM cannot read variable-length arrays; use FXBREAD instead.
• FXBWRITM Write multiple columns/rows to a disk FITS binary table file. A call to FXBWRITM will write multiple rows and multiple columns to a binary table in a single procedure call. Up to fifty columns may be read in a single pass. The file should have already been opened with FXBOPEN (with write access) or FXBCREATE. FXBWRITM optimizes writing multiple columns by first writing a large chunk of data to the FITS file all at once. FXBWRITM cannot write variable-length arrays; use FXBWRITE instead.
• FXHREAD Reads a FITS header from an opened disk file. Reads a FITS header from an opened disk file.
• FXREAD Read basic FITS files. Read the primary array from a disk FITS file. Optionally allows the user to read in only a subarray and/or every Nth pixel.
