…xmin", "ymin", "xmax" and "ymax" flags. The render region bounds that are not specified are calculated automatically as they were before. The user can also now specify a constant tempature offset with the "o_col" flag.
… being less than or equal to the minimum bounds, and also prevented the temperature offset making particle temperatures less than or equal to zero. Lightcurve generation will be aborted in both of these scenarios.
… references to the spectral hardening factor, constant temperature offset and the user defined render region bounds.
…more digits are now truncated to values that can be formatted using an exponent of two digits. This prevents invalid values from being written to the file as ascii pixmaps are written with values that have exponents of two digits. The user is given warnings when the truncation happens.
… be represented with a negative exponent of two digits.
…mits for the largest and smallest values that can be represented with negative expodents of two digits.
…he heap instead of the stack.

… can use the preprocessor.
…uncation will only occur when SPLASH is compiled in double precision mode as it is unnecessary and creates problems in single precision mode. Also added truncation (only in double precision mode) to the header datmin and datmax values for the ascii and ppm pixmaps as they use the same formatting string as the pixel values.

Next review available in: 35 minutes You've used all free OSS reviews for now. Wait for the free limit to reset to keep reviewing this public repository. How can I continue?After more reviews become available, a review can be triggered using the To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews. How do review limits work?CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability. For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

📝 WalkthroughWalkthroughThe change adds exact command-line limit parsing and coordinate-limit overrides. It updates adaptive-limit handling, margin variables, and lightcurve temperature processing. Documentation describes the new options. Pixel-map metadata uses wider scientific formatting. Build prerequisites are updated. ChangesCoordinate limits and rendering

Estimated code review effort: 4 (Complex) | ~45 minutes Mergeability Score: 🟡 Moderate · up to The PR changes command-line limit handling and light-curve flux calculations, but invalid or oversized limits may be silently misprocessed and corrected frequency-dependent flux can diverge from grey flux, producing incorrect results. Merge should wait for these bounded correctness fixes or explicit owner acceptance. Sequence Diagram(s)sequenceDiagram

369-392: 🎯 Functional Correctness | 🟠 Major | ⚡ Quick winWiden the argument buffer in
get_optionto prevent silent truncation of list values.
get_optionreads each command-line argument intocharacter(len=80) :: string.get_command_argumenttruncates without any error.envlistpasses acharacter(len=256)buffer asvalue, andrenvlist/rflaglistuse this path for--limits=...lists (src/limits.f90line 563 requests up to2*maxplotvalues). A long--limits=list is therefore cut at 80 characters, and the parsed values are wrong with no warning.
get_command_option_stringalready detects oversized arguments and reports an error, so the two paths behave inconsistently.🐛 Proposed fix
subroutine get_option(variable,value,err) character(len=*), intent(in) :: variable character(len=*), intent(out) :: value - character(len=80) :: string,optname + character(len=1024) :: string + character(len=80) :: optname integer, intent(out) :: err - integer :: nargs,iarg,ieq + integer :: nargs,iarg,ieq,arglen err = 1 value = '' nargs = command_argument_count() do iarg=1,nargs - call get_command_argument(iarg,string) + call get_command_argument(iarg,string,length=arglen) + if (arglen > len(string)) then + print "(a)",' ERROR: command-line argument too long' + cycle + endif call extract_option_name(string,optname,ieq)🤖 Prompt for AI Agents

Inline comments:
In `@docs/getting-started.rst`:
- Around line 452-456: Update the --limits documentation entries to correct
“columnss” to “columns” and distinguish the 2-value case from the 2*ndim-value
case, explicitly describing how each applies to coordinates.
In `@src/lightcurve.f90`:
- Around line 252-259: Apply the same corrected temperature used for flux_nu to
the grey flux array: compute the effective temperature from dat(i,itemp), f_col,
and o_col once per particle, then derive flux from its fourth power and flux_nu
from B_nu using that value. Update the surrounding logic so non-positive
effective temperatures produce zero in both arrays before interp3D_proj_opacity
receives them.
In `@src/limits.f90`:
- Around line 546-558: Update the --lim validation in the have_lim block to
distinguish a missing value from missing coordinate columns: when
get_command_option returns the sentinel -1., report that --lim requires a
halfwidth value, while retaining the coordinate-column error for valid negative?
values are not valid halfwidths and preserving the existing limit-setting flow
for positive values. Also reject zero halfwidth so --lim=0 cannot create
min==max coordinate limits.
- Around line 559-597: Update the --limits parsing in the have_limits branch to
pass a non-numeric sentinel through rflaglist’s errval argument, then detect any
returned sentinel values and reject the input with an error before applying or
reporting limits. Preserve the existing even-count and column-limit validation
for valid numeric values.
In `@src/splash.f90`:
- Around line 54-60: Align the 4.0.0 changelog entry with the release date in
the version declaration by updating the date in either the entry near the top or
the version value assigned in the version declaration, so both consistently
represent 19 March 2026.
- Around line 1021-1024: Add a changelog entry describing that --xmin and
related options override plot limits, and direct users to --xminmargin,
--xmaxmargin, --yminmargin, and --ymaxmargin for page-margin control. Update the
existing 3.3.1 wording without changing the environment-variable handling in the
margin initialization.
