Build Status

Naive CGo bindings for FITSIO.

Installation

$ go get github.com/astrogo/cfitsio

You, of course, need the C library CFITSIO installed and available through pkg-config.

Documentation

http://godoc.org/github.com/astrogo/cfitsio

Example

import fits "github.com/astrogo/cfitsio"

func dumpFitsTable(fname string) {
	f, err := fits.Open(fname, fits.ReadOnly)
	if err != nil {
		panic(err)
	}
	defer f.Close()

	// get the second HDU
	table := f.HDU(1).(*fits.Table)
	nrows := table.NumRows()
    rows, err := table.Read(0, nrows)
    if err != nil {
        panic(err)
    }
    defer rows.Close()
	for rows.Next() {
        var x, y float64
        var id int64
        err = rows.Scan(&id, &x, &y)
        if err != nil {
            panic(err)
        }
        fmt.Printf(">>> %v %v %v\n", id, x, y)
	}
    err = rows.Err()
    if err != nil { panic(err) }
    
    // using a struct
    xx := struct{
        Id int     `fits:"ID"`
        X  float64 `fits:"x"`
        Y  float64 `fits:"y"`
    }{}
    // using a map
    yy := make(map[string]interface{})
    
    rows, err = table.Read(0, nrows)
    if err != nil {
        panic(err)
    }
    defer rows.Close()
	for rows.Next() {
        err = rows.Scan(&xx)
        if err != nil {
            panic(err)
        }
        fmt.Printf(">>> %v\n", xx)

        if err != nil {
            panic(err)
        }

	}
    err = rows.Err()
    if err != nil { panic(err) }

Functions

func CopyHDU

func CopyHDU(dst, src *File, morekeys int) error

CopyHDU copies the current HDU from the FITS file associated with infptr and append it to the end of the FITS file associated with outfptr. Space may be reserved for MOREKEYS additional keywords in the output header.

func CopyTable

func CopyTable(dst, src *Table) error

CopyTable copies all the rows from src into dst.

func Version

func Version() float32

Version returns the revision number of the CFITSIO library. The revision number will be incremented with each new release of CFITSIO.

func WriteHDU

type File

type File struct {
	// contains filtered or unexported fields
}

File is a handle to a FITS file

func Create

func Create(fname string) (File, error)

Create creates and opens a new empty output FITS file.

func Open

func Open(fname string, mode Mode) (File, error)

Open an existing FITS file Open will create HDU values, loading the Header part but leaving the Data part on disk.

func (*File) CHDU

func (*File) Close

func (f *File) Close() error

func (f *File) Copy(out *File, previous, current, following bool) error

Copy all or part of the HDUs in the FITS file associated with infptr and append them to the end of the FITS file associated with outfptr. If 'previous' is true, then any HDUs preceding the current HDU in the input file will be copied to the output file. Similarly, 'current' and 'following' determine whether the current HDU, and/or any following HDUs in the input file will be copied to the output file. Thus, if all 3 parameters are true, then the entire input file will be copied. On exit, the current HDU in the input file will be unchanged, and the last HDU in the output file will be the current HDU.
