These files are in ASCII and have one record per input value in the form: IIII : BBBBB GGGGG RRRRR where IIII is the input intensity, BBBBB is the blue output intensity, GGGGG is the green output intensity, and RRRRR is the red output intensity. The range 0 to 10000 is scaled to 0.0 to 1.0 for loading to the TV. You must retain this format exactly and have one record for each input value in order of increasing input intensity. These files may be edited by your favorite text editor. Their name is .uuu, where is a 1-8 character name of your choice (in upper case) and .uuu is your user number in extended hexadecimal (base 36, with leading 0's as needed to make 3 characters). The standard AIPS OFMs are kept in an area with the pre-defined logical name AIPSOFM. Use OFMDIR for a list of these files. You may also keep OFM files in any area of your choosing. In that case, specify OFMFILE = ':', where is the logical name of your area (usually in upper case) and the colon is required and implies this usage. The full file name including any extension must be given in this case. Note that the Unix-standard $ ahead of the logical is omitted. Other forms are now acceptable as well (except in OFMGET which requires a logical) OFMFILE = 'MyOFM will find the file in the logical directories AIPSOFM or OFMFIL. A full path name may also be given OFMFILE = '/home/primate2/egreisen/AIPS/Text.ofm if it fits in 48 characters. Note that the trailing quote mark is left off and this is the last command on the input line so that the case is preserved. All verbs which use this adverb are also capable of taking an immediate argument which will override the adverb value. For examples, OFMZAP 'MYAREA:LOUSY.OFM' OFMGET 'COLWED8' Note that the apostrophies are required. Verbs: OFMGET......Load the specified OFM file to the TV OFM. OFMSAVE.....Create a new OFM file of the specified name and fill it with the current OFM. OFMZAP......Delete the specified OFM file. Tasks: GREYS.......Make a grey-scale plot scaled with the OFM. Contours may also be drawn. PCNTR.......Make a grey-scale plot scaled with the OFM. Contours and polarization vectors are also drawn. LWPLA.......Convert a plot file to PostScript for saving and/or printing. The OFM is used to convert grey scales. KNTR........Make a grey-scale plot scaled with the OFM. Contours and polarization vectors can also be drawn. ---------------------------------------------------------------- The AIPSOFM files provided are Black & white ones: BLACK Just as it says - all 0 or black EYEBW The eye perceives this as linear FOTOBW Actually linear GREY01W 1 step wedge GREY02W 2 step wedges GREY04A 4 discreet levels.
