IRAF help page for package noao.nproto, program slitpic

slitpic -- generate IRAF image of slit mask for aperture plates.

slitpic serial_numbers output_root

A range of serial numbers to be searched for in tape1. One mask is generated for each serial_number.

The rootname of the output image file. The serial_number is appended to this output_root if more than one image is begin created.

A text file containing solutions generated by program SLITS. This file essentially contains x,y positions of slits to be included on the mask.

The slit width in seconds of arc.

The telescope site where the output mask will be used. Current choices are "kpno" and "ctio".

The scale of the output image in arcseconds per pixel

The date from which pixel_scale is valid. The output crtpict print will be annotated with this date.

This boolean parameter controls whether or not a file of commands is written to drive program crtpict.

If crtpict = yes, this parameter specifies the root name of the output command file. This command file is read by task crtpict.

Task slitpic reads a file of slit positions and generates an IRAF image for use as a slit mask for aperture plate observing.

The following example creates an IRAF image from the "SERIAL = 67" entry in file "mask67.dat"; the output image is named "mask": .sp

	cl> slitpic 67 mask tape1=mask67.dat

TIME REQUIREMENTS Task slitpic takes 8 cp seconds to create a 780 x 780 mask; a 1184 x 1184 image requires about 16 cp seconds.
