Enter declination for equinox 2000 in degrees, arcminutes, and arcseconds (dd mm ss.s). Omit the "+" sign if the Dec. is >0.
It does not need to be very accurate; the degrees alone should be enough.
You may also input a decimal number (dd.d) for the declination degrees, if you find that more convenient. Be sure to zero the arcminutes and arcseconds, if you choose to use this format.
The declination is needed for background estimation.Hans-Martin Adorf <email@example.com>, ST-ECF
