dopointing script

NAME

dopointing - creates TPoint data file (or FITs data) from starlist

SYNOPSIS

dopointing mode=[index=] [prompt] [noslit] [double]
align mode=skip|paddle|ccd|fits [time=1] [zoom=1] [bin=1] [span=1000] [camera=ccd]

DESCRIPTION

dopointing take the list of stars makepointing.coord created by makepointing and generates the TPoint data file run.dat. Note:if the mode=fits, annotated FITs files are created and these must be analyzed (by fitstotpoint to create the run.dat file.

dopointing does this by first interrogating the telescope server about the name of the observatory, date, temperature, pressure and it puts this data into run.dat Then for each star in the file makepointing.coord it:

Points telescope (twice)
Sets tracking to local value
Execute align script to center telescope
Writes line to run.dat (adding to it if it exists) or generates a FITs file
Executes a slit keepopen command.

All extra arguments are passed to the align script.

There are several ways of centering the star, you must pick one of these by specifying the mode= option:

paddle-asks you to move the telescope manually and center the star.
ccd-puts up a tv image of the star and wait for you to select the star with the cursor.
skip-just points the telescope and generates pointing file. Use this for testing
fits-generates an annotated FITs file of the field These must be analyzed later with fitstotpoint.

The pointing file has two auxiliary measurements. The first is the angular distance from the target in arc-seconds. The second is present for altaz telescopes is the absolute azimuth expressed in turns from due north.

OTHER OPTIONS

See align for image display options.

index= allows you to start observing from the middle of the list.

prompt- will cause you to be asked to move the telescope each time.

noslit- will not issue keepopen command. This option is selected when mode=skip is used.

double- points twice
