The CoRoT space mission routinely provides high-precision photometric measurements of thousands of stars that have been continuously observed for months. The...
Correction of the wavefront using the irradiance transport equation
The correction of the wavefront in optical systems implies the use of wavefront sensors, software, and auxiliary optical systems. We propose evaluated the...
Correction to ATEL #233 (2S 1711-339) and addendum to ATEL #205 (A1744-36)
2S 1711-339: In ATEL #233 the absorbed X-ray flux of 2S 1711-339 was incorrectly given as 2e-15 ergs cm-2 s-1 (0.3-7.0 keV). The correct value obtained by using...
Correction to ATEL 871: A Swift/XRT observation of Aql X-1 during its recent outburst
In ATEL #871 the fluxes were incorrectly quoted. All the fluxes should be multiplied by 1E-10 in order to obtain the correct values. The quoted luminosities are...
Correlation of PN Morphologies and Nebular Parameters
A study of the correlation of the morphology of a complete sample of 255 galactic planetary nebulae (PNe) with their nebular parameters is presented here...
Correlations between Structural Parameters of Disk Galaxies
We have obtained (in BVRI filters) the structural parameters of four disk galaxies, spanning a range of different morphological types. We believe the parameters...
