To read your data into IRAF you need the images in FITS format. If you are not at the Observatory you need a tape of the images in FITS format. If you are working at the Schmidt, you can transfer images directly as follows.
On the FLAIR PC you can convert your images to FITS format using the local programme fitsout2. This is described in the FLAIR PC Guide (note that fitsout2 is an improved version of the original fitsout described). Note that the files are still not in legal FITS format and need correcting (see below). The images may then be transferred to whichever computer you use for the subsequent analysis using ftp:
$ ftp aatssa username password binary mput *.fts bye
The final step is to convert the FITS images into IRAF images using the IRAF task rfits. This same command may be used to read both FITS tapes and FITS images on disk:
rfits dir/*.fts 1 flair # disk example rfits mta 1-999 flair # tape example
The image headers as written by the FLAIR PC contain some entries not recognised by IRAF. For example, the date needs to be in the format dd/mm/yy rather than dd:mm:yy. The task fixhead corrects this automatically. It also performs a number of other useful functions: correction of UT for each image, changing R.A. and Dec. to that which is desired, and setting the epoch. The changes made are as follows. The package astutil must be loaded before running fixhead.
lparam fixhead # An example set of parameters for the task fixhead images = ../raw/*.imh Image(s) to fix (root = "flair") New root name (changecor = no) Change RA and Dec? (ra = 12.45) New RA (dec = 13.5) New Dec (epoch = 1950.) Epoch (fixpix = yes) Fix negative pixels? (remove = no) Remove original files? (show = no) Print operations? (imglist = "") (mode = "ql")
At this stage a printed list of the images may prove useful:
imhead flair*.imh long- | lprint
