Station X09 - Deep Random Survey, Rio Hurtado; lat -30.52636, lon -70.85330, height 1737 m.
Target altitude and azimuth use MPC MPES perturbed ephemerides when available, with a local TXT RA/DEC fallback. V Star is an approximate Johnson V value from the nearest Gaia DR3 catalog star to the TXT position. Diameters use JPL SBDB first and fall back to an MPC H estimate. MPC and Gaia uncertainties are included in hovers when available. The Sun column turns red when the Sun is not below the apparent horizon threshold of -0.833 degrees.

Scatter diagrams
The three pairwise combinations of dt, V Star and Exp. are shown below. In each chart the third variable is encoded as equal-area circles; rows with incomplete plotted values are omitted. Colors mark operational warnings: red means dt < 2 x Exp., orange means dt < Real, purple means nautical twilight, and blue means no plotted warning. Click a point to jump to its table row.
dt axis:
normaldt < Realdt < 2 x Exp.nautical twilightdt = Realdt = 2 x Exp.
dt vs V Star
The horizontal axis is dt. The vertical axis is V Star; brighter stars are at the top. Circle area is proportional to Exp.
dt vs Exp
The horizontal axis is dt and the vertical axis is exposure time. Circle area is proportional to the star brightness derived from V Star, so brighter stars are larger.
V Star vs Exp
The horizontal axis is V Star, with brighter stars at the left. The vertical axis is exposure time. Circle area is proportional to dt.
