J/A+A/405/627     Angular dimensions of 312 planetary nebulae   (Tylenda+, 2003)

Angular dimension of planetary nebulae Tylenda R., Siodmiak N., Gorny S.K., Corradi R.L.M., Schwarz H.E. <Astron. Astrophys. 405, 627 (2003)> =2003A&A...405..627T
ADC_Keywords: Planetary nebulae Keywords: planetary nebulae: general Description: We present the results of direct measurements done on Hα (or Hα+[NII]) images of 312 planetary nebulae. For each planetary nebulae deconvolved FWHM and resolution size from Gaussian fit and from second-moment method and direct measurement at 10% level are presented. File Summary:
