+NAME
+slitpic -- generate IRAF image of slit mask for aperture plates.
+.ih
+USAGE
+slitpic serial_numbers output_root
+.ih
+PARAMETERS
+.ls serial_numbers
+A range of serial numbers to be searched for in \fItape1\fR.  One
+mask is generated for each \fIserial_number\fR.
+.le
+.ls output_root
+The rootname of the output image file.  The \fIserial_number\fR is appended to
+this \fIoutput_root\fR if more than one image is begin created.
+.le
+.ls tape1 = "slitsave"
+A text file containing solutions generated by program SLITS.  This file
+essentially contains x,y positions of slits to be included on the mask.
+.le
+.ls slit_width = 2.5
+The slit width in seconds of arc.
+.le
+.ls site = "kpno"
+The telescope site where the output mask will be used.  Current choices 
+are "kpno" and "ctio". 
+.le
+.ls pixel_scale = 0.4157
+The scale of the output image in arcseconds per pixel
+.le
+.ls pixel_scale_date = "14feb84"
+The date from which \fIpixel_scale\fR is valid.  The output \fBcrtpict\fR
+print will be annotated with this date.
+.le
+.ls crtpict = no
+This boolean parameter controls whether or not a file of commands is written
+to drive program \fBcrtpict\fR.
+.le
+.ls cmd_file = "cmd"
+If \fIcrtpict\fR = yes, this parameter specifies the root name of the output
+command file.  This command file is read by task \fBcrtpict\fR.
+.le
+.ih
+DESCRIPTION
+Task \fBslitpic\fR reads a file of slit positions and generates an IRAF
+image for use as a slit mask for aperture plate observing.
+.ih
+EXAMPLES
+The following example creates an IRAF image from the "SERIAL = 67" entry
+in file "mask67.dat";  the output image is named "mask":
+.sp
+.nf
+	cl> slitpic 67 mask tape1=mask67.dat
+.fi
+.ih
+TIME REQUIREMENTS
+Task \fBslitpic\fR takes 8 cp seconds to create a 780 x 780 mask;  a
+1184 x 1184 image requires about 16 cp seconds.
